MILL RUN, Pa. — An overflowing stream after heavy rain toppled a large bronze statue at architect Frank Lloyd Wright’s renowned Fallingwater house in Pennsylvania, officials said.

The flooding early Saturday was from Bear Run, which flows beneath the national historic landmark in Fayette County. A fallen tree hit a wall and apparently dislodged the ‘‘Mother and Child’’ statue from its place, said Lynda Waggoner, of the Western Pennsylvania Conservancy. The interior of the home wasn’t damaged.

‘‘It’s one of our most significant works here at Fallingwater,’’ Waggoner said of the Jacques Lipchitz sculpture. ‘‘It’s one that the house has come to be identified with. The first view, when you’re on the bridge, looking at the house — it’s right there.’’

Waggoner said the statue was submerged in the creek, held up by a chain that was installed after a 1956 flood, but was removed after the water level dropped. It is being assessed for damage.

She said workers would try to repair the wall and move the statue back into place.

Trees by the guest house were also damaged after Bear Run ‘‘rose to a deluge,’’ Waggoner said. Debris was visible on stairs leading down from the first floor of the main house to the stream.

Fallingwater, built over a waterfall for the Kaufmann family, who owned a Pittsburgh department store, is now operated as a museum by the conservancy.

Lipchitz’s statue depicts a woman with her arms outstretched and a child clinging to her neck.
