WASHINGTON (RNS) A 500-foot crane toppled over next to the Washington National Cathedral on Wednesday (Sept. 7), adding to the earthquake damage that the crane was brought in to fix.

The 500-ton crane crushed several cars and took part of the roof off the Herb Cottage, a small building adjacent to the cathedral.

No one was seriously injured by the crane, which fell near a walkway used by students at the cathedral’s two affiliated schools.

Before it fell, an operator was using the crane to raise materials to the church’s roof, where engineers are removing debris and stabilizing structures damaged in a 5.8-magnitude earthquake that rocked the East Coast on Aug. 23.

The cathedral’s spires, flying buttresses and other structures suffered considerable damage during the quake, and repairs are expected to take years and cost millions.

The cathedral has been closed to the public and netting has been erected to protect from falling debris, but President Obama is slated to speak at a 9/11 memorial concert at the cathedral on Sunday.
