NEW LONDON, Conn. — An historic Connecticut church’s soaring steeple and roof collapsed on Thursday, leaving a gaping hole in the top of the building and the front reduced to a heap of rubble.

The cause of the collapse at the First Congregational Church in downtown New London was not immediately known. No injuries were reported, city and church officials said in posts on Facebook.

Rescue teams and State Police search dogs responded after the collapse. Efforts by first responders were still underway late Thursday afternoon to confirm that no one had been hurt, U.S. Rep. Joe Courtney, who represents New London, said in a statement.

The stone building dates to around 1850, according to state building records, though the congregation dates back to the mid-1600s, its website says.

The Engaging Heaven Church, which also worships in the space, said on Facebook that it wasn’t aware of anyone inside at the time of the collapse.

Phone calls left for the congregation and Engaging Heaven were not immediately returned.
