Opera house vs Eiffel Tower

Informations

The Sydney Opera House is a multi-venue performing arts Center at Sydney Harbour in Sydney, New South Wales, Australia.

It is among the 20th century's most famous and distinctive buildings.Designed by Danish architect Jørn Utzon, but completed by an Australian architectural group headed up by Peter Hall, the building was officially opened on 20 October 1973 after a gestation beginning with Utzon's 1957 choice as winner of an international design competition. The Government of New South Wales, led by the premier, Joseph Cahill, authorised work to start in 1958 with Utzon directing construction. The government's decision to construct Utzon's design is often overshadowed by conditions that followed, including cost and scheduling overruns as well as the architect's ultimate resignation.The building and its surrounds occupy all of Bennelong Point on Sydney Harbour, between Sydney Cove and Farm Cove, adjacent to the Sydney central business district and the Royal Botanic Gardens, and close by the Sydney Harbour Bridge. The construction comprises multiple performance venues, which together host well over 1,500 performances annually, attended by over 1.



2 million people. Performances are presented by numerous performing artists, including three resident companies: Opera Australia, the Sydney Theatre Company and the Sydney Symphony Orchestra. As one of the most popular visitor attractions in Australia, the website is visited by over eight million people annually, and approximately 350,000 visitors take a guided tour of the building each year. The building is managed by the Sydney Opera House Trust, an agency of the New South Wales State Government. On 28 June 2007, the Sydney Opera House became a UNESCO World Heritage Site, having been listed on the (now defunct) Register of the National Estate since 1980, the National Trust of Australia register since 1983, the City of Sydney Heritage Inventory since 2000, the New South Wales State Heritage Register since 2003, and the Australian National Heritage List as 2005. Moreover, the Opera House was a finalist at the New7Wonders of Earth campaign list.

The Eiffel Tower ( EYE-f?l; French: tour Eiffel [tu???f?l] (listen)) is a wrought-iron lattice tower on the Champ de Mars in Paris, France. It's named after the engineer Gustave Eiffel, whose firm designed and built the tower. Constructed from 1887 to 1889 as the entrance to the 1889 World's Fair, it was initially criticised by a number of France's leading artists and intellectuals for its design, but it has become a worldwide cultural icon of France and one of the most recognisable structures on the planet. The Eiffel Tower is the most-visited paid monument in the world; 6.91 million people ascended it in 2015. The tower is 324 metres (1,063 ft) tall, about the same height as an 81-storey construction, and also the tallest structure in Paris. Its base is square, measuring 125 metres (410 ft) on each side. During its construction, the Eiffel Tower surpassed the Washington Monument to become the tallest man-made structure in the world, a title it held for 41 years until the Chrysler Building in New York City was completed in 1930. It was the first structure to reach a height of 300 metres. Due to the addition of a broadcasting aerial at the top of the tower in 1957, it is now taller than the Chrysler Building by 5.2 metres (17 ft). Excluding transmitters, the Eiffel Tower is the second tallest freestanding construction in France after the Millau Viaduct. The tower has three levels for people, with restaurants on the first and second degrees. The top level's upper stage is 276 m (906 ft) above the floor -- the maximum observation deck available to the general public in the European Union. Tickets can be bought to ascend by lift or stairs to the first and second degrees. The climb from ground level to the first level is over 300 steps, as is the climb in the first level to the second. Although there is a staircase to the top level, it is usually available only by lift.
