The tower's height has increased over the decades due to the addition of various broadcasting antennas. The most recent addition in 2022 was a new antenna dedicated to digital terrestrial radio (DAB+), which added 6 meters to the structure's total height [toureiffel.paris](https://www.toureiffel.paris/en/news/history-and-culture/133-years-and-1083-feet).

The tower was originally constructed for the 1889 Paris World Exhibition and was the tallest man-made structure in the world until the Chrysler Building was completed in 1930 [structurae.net](https://structurae.net/en/structures/eiffel-tower).

What was the original height of the Eiffel Tower before any antennas were added?
