A 500-ton construction crane collapsed at Washington's National Cathedral on Wednesday as the remnants of Tropical Storm Lee passed through the area.

The crane flipped backwards at around 11:00 a.m. Wednesday according to the D.C. fire department, falling onto five cars and two cathedral buildings. No one was seriously injured, though one person was taken to a local hospital with non-life-threatening injuries.

Officials are now investigating what caused the crane to tip over, though heavy rain and wind were pounding the Washington area at the time.

Construction crews were lifting a steel beam to the roof area with the 500-foot crane extended 350 feet in the air at the time of the collapse.

As they were returning to take more steel I-beams up there, the crane somehow malfunctioned and collapsed, Timothy Gerhart, assistant chief of operations, DC Fire and EMS, told ABC news.

A cathedral spokesman said that the crane damaged Church House, which houses members of the diocese, and Herb Cottage, which houses the gift shop. Luckily, no one was in either building at the time of the collapse.

The crane was working to fix damage at the Cathedral from the 5.8 earthquake on Aug 23. Three of the four main spires were damaged in the quake, causing millions of dollars in damages. Additionally, an oak tree was blown down in front of the cathedral during Hurricane Irene's romp up the East Coast, causing minor damage.

Crews were scrambling to prepare the historic church for a reopening this weekend for a variety of Sept. 11 memorial events.

President Obama is scheduled to speak at an interfaith ceremony there on the evening of Sept. 11.
