This black-and-white historical photograph captures the ruins of a large, masonry building following the 1906 San Francisco earthquake and fire. The structure, a mix of Romanesque and Gothic architectural styles, features a prominent square tower with a peaked roof and several arched entryways and windows. Much of the roof is missing, and the interior is hollowed out, leaving only the scorched and crumbling stone and brick exterior walls standing. The surrounding ground is a flat, desolate expanse of dirt and debris, with scattered bricks and stones in the foreground. In the background, a few utility poles with hanging wires are visible against a pale, hazy sky, and the distant horizon shows the leveled remains of other city structures. In the bottom right corner of the image, the white text "Miles Bros 73" is etched into the print.
