In the game
The broken obelisk still towers over the Mall. The Brotherhood of Steel holds it, and repairing its elevator lets Galaxy News Radio reach the whole Capital Wasteland.
The real place
Completed in 1884, the 555-foot marble obelisk was the tallest structure in the world until the Eiffel Tower.
Visiting
An elevator runs to the 500-foot observation level; free timed tickets are released in advance.
