## Response

The Eiffel Tower was completed on **March 31, 1889**, after 2 years, 2 months, and 5 days of construction [toureiffel.paris](https://www.toureiffel.paris/en/news/history-and-culture/133-years-and-1083-feet). Including antennas, its current height is **330 meters (1,083 feet)**, a milestone reached on March 15, 2022, with the helicopter installation of a new DAB+ digital terrestrial radio antenna [toureiffel.paris](https://www.toureiffel.paris/en/news/history-and-culture/300-330-meters-story-towers-height).

When originally inaugurated, the Tower stood at 312 meters (1,024 feet) with its flagpole. The height increased in stages over the decades — reaching 320.75 meters in 1957 with the addition of television antennas, 324 meters in 2000 with a new UHF antenna for digital terrestrial television, and finally 330 meters in 2022 [toureiffel.paris](https://www.toureiffel.paris/en/news/history-and-culture/300-330-meters-story-towers-height). The metal frame alone weighs 7,300 tons, and the total weight of the structure is 10,100 tons [toureiffel.paris](https://www.toureiffel.paris/en/the-monument/key-figures).

Would you like to know how its height compares to other famous structures around the world?
