99 S Van Ness, San Francisco

This huge public storage facility is at the intersection of South Van Ness Avenue and 12th Street, San Francisco.

The building dates from 1935 and besides some wonderful Art Deco decoration on towers at each end and at the obtuse corner where the roads meet, it also has a lighthouse or lookout tower.
