Christ the Redeemer (BRAZIL)

Image result for jesus christ in brazil
DesignerCreated by French sculptor Paul Landowski and built by the engineer Heitor da Silva Costa Brazil in collaboration with the French engineer Albert Caquot.
Height30 metres (98 ft) and 38 metres (125 ft) tall with its pedestal
Completion dateDedicated October 12, 1931
Christ the Redeemer (Portuguese): Cristo Redentorstandard Brazilian Portuguese: is an Art Deco statue of Jesus Christ in Rio de JaneiroBrazil, created by French sculptor Paul Landowski and built by the Brazilian engineer Heitor da Silva Costa, in collaboration with the French engineer Albert Caquot. It is 30 metres (98 ft) tall, not including its 8-metre (26 ft) pedestal, and its arms stretch 28 metres (92 ft) wide.
The statue weighs 635 metric tons (625 long, 700 short tons), and is located at the peak of the 700-metre (2,300 ft) Corcovadomountain in the Tijuca Forest National Park overlooking the city of Rio. As a symbol of Brazilian Christianity, the statue has become an icon for Rio de Janeiro and Brazil. It is made of reinforced concrete and soapstone, and was constructed between 1922 and 1931.
The idea of building a large statue atop Corcovado was first suggested in the mid- 1850 s, when Vincentian priest, Pedro Maria Boss, suggested placing a Christian monument on Mount Corcovado to honour Princess Isabel, princess regent of Brazil and the daughter of Emperor Pedro II, although the project was never approved. In 1889, the country became a republic and, with the official separation of state and church, the idea was dismissed.
The second proposal for a landmark statue on the mountain was made in 1920, by the Catholic Circle of Rio. The group organized an event called Semana do Monumento("Monument Week") to attract donations and collect signatures to support the building of the statue. The donations came mostly from Brazilian Catholics. The designs considered for the "Statue of the Christ" included a representation of the Christian cross, a statue of Jesus with a globe in his hands, and a pedestal symbolizing the world. The statue of Christ the Redeemer with open arms, a symbol of peace, was chosen.
Local engineer Heitor da Silva Costa designed the statue; it was sculpted by Polish-French sculptor Paul Landowski.
The face of the statue was created by Romanian sculptor Gheorghe Leonida, who was born in Galati, Romania, in 1893. He studied sculpture at the Fine Arts Conservatory in Bucharest, then, after three more years' study in Italy, he won a prize for the sculpture Reveil("Awakening"). After that he moved to Paris, where his work, Le Diable ("The Devil"), was awarded the Grand Prix. Becoming famous in France as portraitist, he was included by Paul Landowski in the team that started working on Christ the Redeemer in 1922. Gheorghe Leonida contributed by portraying Jesus Christ's face on the statue, which made him famous.
A group of engineers and technicians studied Landowski's submissions and the decision was made to build the structure out of reinforced concrete (designed by Albert Caquot) instead of steel, more suitable for the cross-shaped statue. The outer layers are soapstone, chosen for its enduring qualities and ease of use. Construction took nine years, from 1922 to 1931 and cost the equivalent of US$250,000($3,300,000 in 2015). The monument was opened on October 12, 1931. During the opening ceremony, the statue was lit by a battery of floodlights turned on remotely byshortwave radio pioneer Guglielmo Marconi, stationed 5,700 miles (9,200 km) away in ROME
 in 2010, a massive restoration of the statue was undertaken. The statue was washed, the mortar and soapstone that cover the statue were replaced, the internal structure of iron was restored, and the monument was made waterproof. One incident which occurred during the restoration, was an act of vandalism, wherein paint was sprayed along the arm. Mayor Eduardo Paes called the act "a crime against the nation". The culprits later apologised and presented themselves to the police.[14][15][16]The statue was struck by lightning during a violent thunderstorm on February 10, 2008, and suffered some damage to the fingers, head and eyebrows. A restoration effort was put in place by the Rio de Janeiro state government to replace some of the outer soapstone layers and repair the lightning rods installed on the statue. It was damaged by lightning again, on January 17, 2014, where a finger on the right hand was dislodged.

Restoration[edit]

A close-up view of the face
In 1990, restoration work was conducted through an agreement among several organizations, including the Archdiocese of Rio de Janeiro, media company Rede Globo, oil company Shell do Brasil, environmental regulator IBAMANational Institute of Historic and Artistic Heritage, and the city government of Rio de Janeiro.
More work on the statue and its environs was conducted in 2003 and early 2010. In 2003, a set of escalators, walkways, and elevators were installed to facilitate access to the platform surrounding the statue. The four-month restoration in 2010 focused on the statue itself. The statue's internal structure was renovated and its soapstone mosaic covering was restored by removing a crust of fungi and other microorganisms and repairing small cracks. The lightning rods located in the statue’s head and arms were also repaired, and new lighting fixtures were installed at the foot of the statue.
The restoration involved one hundred people and used more than 60,000 pieces of stone taken from the same quarry as the original statue.During the unveiling of the restored statue, it was illuminated with green-and-yellow lighting in support of the Brazil national football team playing in the 2010 FIFA World Cup.
Maintenance work needs to be conducted periodically due to the strong winds and erosion to which the statue is exposed, as well as lightning strikes. The original pale stone is no longer available in sufficient quantities, and replacement stones are increasingly darker in hue.

Twin towers (USA)

The World Trade Center is a partially completed complex of buildings, under construction, in Lower ManhattanNew York City,United States, replacing an earlier complex of seven buildings with the same name on the same site. The original World Trade Center featured landmark twin towers, which opened on April 4, 1973, and were destroyed in the September 11 attacks of 2001, along with 7 World Trade Center. The other buildings in the complex were severely damaged by the collapse of the twin towers, and their ruins were eventually demolished. The site is being rebuilt with six new skyscrapers, a memorial to those killed in the attacks, and atransportation hubOne World Trade Center, the tallest building in the United States, is the lead building for the new complex, reaching more than 100 stories[16] upon its completion in November 2014.[17]
At the time of their completion, the "Twin Towers" — the original 1 World Trade Center, at 1,368 feet (417 m); and 2 World Trade Center — were the tallest buildings in the world. The other buildings in the complex included the Marriott World Trade Center (3 WTC), 4 WTC5 WTC6 WTC, and 7 WTC. All these buildings were built between 1975 and 1985, with a construction cost of $400 million ($2,300,000,000 in 2014 dollars).[18] The complex was located in New York City's Financial District and contained 13,400,000 square feet (1,240,000 m2) of office space.[19][20]
The World Trade Center experienced a fire on February 13, 1975,[21] a bombing on February 26, 1993,[22] and a robbery onJanuary 14, 1998.[23] In 1998, the Port Authority decided to privatize the World Trade Center, leasing the buildings to a private company to manage, and awarded the lease to Silverstein Properties in July 2001.[24]
On the morning of September 11, 2001Al-Qaeda-affiliated hijackers flew two Boeing 767 jets into the complex, beginning with the North Tower at 8:46 AM then the South Tower at 9:03 AM, in a coordinated act of terrorism. After burning for 56 minutes, the South Tower collapsed at 9:59 AM. 29 minutes later, the North Tower collapsed. The attacks on the World Trade Center killed 2,753 people.[25] Falling debris from the towers, combined with fires that the debris initiated in several surrounding buildings, led to the partial or complete collapse of all the other buildings in the complex and caused catastrophic damage to ten other large structures in the surrounding area (including the World Financial Center); three buildings in the World Trade Center complex collapsed due to fire-induced structural failure,[26] and when the North Tower collapsed, debris fell on the nearby 7 World Trade Center building (7 WTC), damaging it and starting fires so that it eventually collapsed.[27][28] The process of cleaning up and recovery at the World Trade Center site took eight months.[29][30]
Over the following years, plans were created for the reconstruction of the World Trade Center. The Lower Manhattan Development Corporation (LMDC), established in November 2001 to oversee the rebuilding process,[31] organized competitions to select a site planand memorial design.[32] Memory Foundations, designed by Daniel Libeskind, was selected as the master plan;[33] however, substantial changes were made to the design.[34]
The first new building at the site was the 7 World Trade Center, which opened in May 2006.[5] The memorial section of the National September 11 Memorial & Museum opened on September 11, 2011[35] and the museum opened in May 2014.[36] 1 World Trade Center opened on November 3, 2014;[17] the 4 World Trade Center opened on November 13, 2013;[4] the 3 World Trade Center is under construction and expected to open in 2017;[37][38] As of November 2013, according to an agreement made with Silverstein Properties Inc., the 2 World Trade Center will not be built to its full height until sufficient leasing is established to make the building financially viable;[39] and 5 World Trade Center will be developed by the Port Authority of New York and New Jersey, but, as of February 2014, a schedule was not confirmed.[40]

Before the World Trade Center

The western portion of the World Trade Center site was originally under the Hudson River, with the shoreline in the vicinity of Greenwich Street. It was on this shoreline close to the intersection of Greenwich and the former Dey Street that Dutch explorerAdriaen Block's ship, the Tyger, burned to the waterline in November 1613, stranding Block and his crew and forcing them to overwinter on the island. They built the first European settlement in Manhattan. The remains of the ship were buried under landfill when the shoreline was extended starting in 1797, and were discovered during excavation work in 1916. The remains of a second ship from the eighteenth century were discovered in 2010 during excavation work at the site. The ship, believed to be a Hudson Riversloop, was found just south of where the Twin Towers used to stand, about 20 feet below the surface.[41]
Later, the area became Radio Row. New York City's Radio Row, which existed from 1921 to 1966, was a warehouse district on theLower West Side in the Financial District. Harry Schneck opened City Radio on Cortlandt Street in 1921, and eventually the area held several blocks of electronics stores, with Cortlandt Street as its central axis. The used radios, war surplus electronics (e.g., ARC-5radios), junk, and parts often piled so high they would spill out onto the street, attracting collectors and scroungers. According to a business writer, it also was the origin of the electronic component distribution business.[42]
The idea of establishing a World Trade Center in New York City was first proposed in 1943. The New York State Legislature passed a bill authorizing New York Governor Thomas E. Dewey to begin developing plans for the project[43] but the plans were put on hold in 1949.[44] During the late 1940s and 1950s, economic growth in New York City was concentrated in Midtown Manhattan. To help stimulate urban renewal in Lower Manhattan, David Rockefeller suggested that the Port Authority build a World Trade Center in Lower Manhattan.[45]
Plans for the use of eminent domain to remove the shops in Radio Row bounded by VeseyChurchLiberty, and West Streets began in 1961 when the Port Authority of New York and New Jersey was deciding to build the world's first world trade center. They had two choices: the east side of Lower Manhattan, near the South Street Seaport; and the west side, near the H&M station, Hudson Terminal.[46](p56) Initial plans, made public in 1961, identified a site along the East River for the World Trade Center.[47] As a bi-state agency, the Port Authority required approval for new projects from the governors of both New York and New Jersey. New Jersey Governor Robert B. Meyner objected to New York getting a $335 million project.[48] Toward the end of 1961, negotiations with outgoing New Jersey Governor Meyner reached a stalemate.[49]
At the time, ridership on New Jersey's Hudson and Manhattan Railroad (H&M) had declined substantially from a high of 113 million riders in 1927 to 26 million in 1958 after new automobile tunnels and bridges had opened across the Hudson River.[50] In aDecember 1961 meeting between Port Authority director Austin J. Tobin and newly elected New Jersey Governor Richard J. Hughes, the Port Authority offered to take over the Hudson & Manhattan Railroad to have it become the Port Authority Trans-Hudson (PATH). The Port Authority also decided to move the World Trade Center project to the Hudson Terminal building site on the west side of Lower Manhattan, a more convenient location for New Jersey commuters arriving via PATH.[49] With the new location and Port Authority acquisition of the H&M Railroad, New Jersey agreed to support the World Trade Center project.[51] In compensation for Radio Row business owners' displacement, the PANYNJ gave each business $3,000 each, without regard to how long the business had been there or how prosperous the business was.[46](p68) After the area had been purchased for the World Trade Center in March 1964,[52] Radio Row was demolished starting in March 1965.[53] It was completely demolished by 1966.[54]
Approval was also needed from New York City Mayor John Lindsay and the New York City Council. Disagreements with the city centered on tax issues. On August 3, 1966, an agreement was reached that the Port Authority would make annual payments to the City in lieu of taxes for the portion of the World Trade Center leased to private tenants.[55] In subsequent years, the payments would rise as the real estate tax rate increased.[56]

Palm island in dubai



The Palm Islands are two artificial islandsPalm Jumeirah and Palm Jebel Ali, on the coast of DubaiUnited Arab Emirates. As at November 2014, only Palm Jumeirah has been completed. This island takes the form of a palm tree, topped by a crescent. When complete, Palm Jebel Ali will take a similar shape; both islands will be host to a large number of residential, leisure and entertainment centres and will add a total of 520 kilometres of non-public beaches to the city of Dubai.
The creation of the Palm Jumeirah began in June 2001. Shortly after, the Palm Jebel Ali was announced and reclamation work began. A third island was planned and construction started, but this project was later remodelled and renamed to Deira Island.
The Palm Islands are artificial islands constructed from sand dredged from the bottom of the Persian Gulf by the Belgian company, Jan De Nul and the Dutch company, Van Oord. The sand is sprayed from dredging ships, guided by a Global Positioning System, onto the required area. The spraying process is known as rainbowing because of the rainbow-like arcs produced in the air when the sand is sprayed. The outer edge of each palm's encircling crescent is a large rock breakwater. The breakwater of the Palm Jumeirah contains over seven million tons of rock; each rock was placed individually by a crane, its position signed off by a diver, and given a Global Positioning System coordinate.[citation needed]
The Jan De Nul Group started working on the Palm Jebel Ali in 2001 and had finished by the end of 2006. The reclamation project for the Palm Jebel Ali includes the creation of a four-kilometer-long peninsula, protected by a 200-meter-wide, seventeen-kilometer long circular breakwater. There are 210,000,000 cubic meters of rock, sand and limestone that were reclaimed (partly originating from the Jebel Ali entrance channel dredging work). There are approximately 10,000,000 cubic meters of rocks in the Slope Protection Works.
