Ocean Beach Pavilion viewed from Great Highway. Seal Rock Hotel at far left. Numerous horse drawn carriages and crowds of people on highway. Built in 1884, it contained a giant ballroom that could hold 2,000 people at a time. The building had bars, restaurants, and a boxing gym that was once used by the first African-American heavyweight champion, Jack Johnson. After many conversions and remodelings, the Pavilion was demolished in 1972.
