Natatorium of the Olympic Club City Clubhouse (1912), San Francisco. Built in 1912 based on a design by architects Charles Paff and John Baur, the historic Natatorium pool of the City Clubhouse is crowned with two enormous oval domes of 39 by 36 feet each. The stained glass domes were restored by Allen Dragge/Reflection Studios in 1986, employing a proprietary earthquake restraint system which enabled them to survive the 1989 earthquake without damage to the glass, even though there was considerable damage elsewhere in the building.
