It's owned by Heron International and is still popularly known as Heron Tower, though following a naming dispute in 2014 involving the tenant Salesforce.com that the City of London planning committee made it clear they would rule in favour of the property being officially named 110 Bishopsgate, even though the application was withdrawn before it went to committee. The tower originally struggled to attract tenants at the depths of the Great Recession, but is now fully let.

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.
