A spokesman for Washington National Cathedral says at least three of the four pinnacles on the central tower have fallen off and the central tower appears to be leaning.
The pinnacles are the top stones on the cathedral's towers.
Richard Weinberg, director of communications for the cathedral, said the cathedral has been evacuated and stone masons are assessing the damage.
The Washington National Cathedral is an Episcopal Church landmark in the nation's capital. Located in the northwest quadrant of the city near foreign embassies and the vice president's residence, the gothic-like structure is among the tallest in the city. It's historically been the site of funerals and memorials for presidents and statesmen.
