Rincon Center (Rincon Annex Post Office)

Rincon Center is a full city block of offices, shops, and residences marked by the Streamline Moderne curves of the former Rincon Annex Post Office. You can identify this historic portion of the complex by the stone relief friezes of dolphins carved above its doorways and windows. Completed in nineteen forty, the post office was once the busiest in San Francisco and occupies the site where a cove known as Rincon once met the bay.
