Two little girls, accompanied by a woman, are running across the lawn on the near side of the club house at San Antonion park. The building has a masonry, two-story tower-like structure at left, and an open pavilion with a conical roof and concrete supporting towers at right center. The pavilion has a semi-circular concrete floor, which is the roof for the glassed-in area below. The entire theme is circular: tower, concrete floor, and pavilion roof. From DeWitt Jones, Oakland Parks and Playgrounds, 1935: Originally called Independence Square when it was deeded to the city of Brooklyn in 1854, this was known as Independence Park at the time Brooklyn was annexed to Oakland in 1872. It is the oldest public grounds in Oakland. In the old days it was the site of bullfights, bull and bear fights, horse races and fiestas, and was also used as an execution grounds and as a signal site for announcing arrivals and departures of ships from Embarcadero San Antonio.
