The Washington Monument was closed Sunday after repeated problems with an elevator, a National Mall and Memorial Parks official said.
"Shortly after opening, the doors got stuck closed again, and we had to evacuate visitors", Litterst said.
The National Park Service says in a statement the monument opened briefly Sunday morning before the elevator got stuck at the 490 feet level. He said two employees and a park service volunteer were in the elevator at the time. The observation deck is at the 500 foot level. Sgt. Anna Rose, a U.S. Park Police spokeswoman said everyone in the monument was evacuated safely.
The elevator has been shut down 24 times since the Washington Monument reopened in May 2014 following repairs for natural disaster damage in 2011.
Park Service said the elevator shut down because of computer problems in its control system.
