The Eiffel Tower’s height was increased to 330 meters in 2022.
The increase came from a new digital-radio antenna, which was hoisted onto the tower on March 15, 2022. The antenna added roughly six meters, raising the structure from 324 meters to its current listed height of 330 meters.
This was not a reconstruction of the tower’s iron frame. The original tower was built between 1887 and 1889 for the Exposition Universelle, and its height has changed several times as broadcasting equipment was added or replaced.
A common mix-up is 1957, when a broadcast antenna raised the tower to about 320.75 meters. Later antenna changes produced heights of 317.96 meters in 1991–1994 and 318.7 meters in 1994–2000. The 2022 antenna is what brought the Eiffel Tower to 330 meters.
