SAN FRANCISCO -- A fire early Sunday destroyed the fourth floor and roof of a historic landmark on Fisherman's Wharf, authorities said.

No injuries were reported.

The fire at Haslett Warehouse was contained by late Sunday morning, but about 90 firefighters remained at the scene. "We're not calling it under control because we still have a lot of heat in the heavy timbers," said Capt. Pete Howes.

Investigators had not determined the cause of the fire.

The building's brick facade remained standing, but firefighters kept spectators away from the structure as a precaution in case of collapse, Howes said.

The building was built around 1907 and was undergoing renovations.

The warehouse is adjacent to The Cannery shopping center, which remained closed Sunday. Some of the 30 shops and restaurants had smoke and fire damage and would remained closed until cleanup was finished, said Kris Kremers, marketing director for the shopping center.

Most businesses on the wharf had closed when the fire broke out around midnight, fire Lt. Eric Richardson said.

Flames also damaged adjacent buildings.
