Sunol Water Temple, Historic water temple pavilion in Sunol, California.

The Sunol Water Temple stands as a 59-foot-high classical pavilion featuring twelve concrete Corinthian columns supporting a conical red tile roof, designed by architect Willis Polk in 1910.

Built in 1910 by the Spring Valley Water Company, the temple marked the confluence of three water sources that supplied San Francisco before the city acquired the facility in 1930 for $40 million.

The ceiling panels were painted by Yun Gee and other artists, showing a Native American maiden carrying water vessels and women in classical poses. The temple also bears an inscription quoting Isaiah 41:18 and Psalms 46:4, ending with "S.V.W.C. MCMX", the Spring Valley Water Company and the year 1910.

The temple is at 505 Paloma Way in Sunol and is open to the public Monday to Friday, 9 a.m. to 3 p.m. The site was restored from 1997 to 2001 with seismic and accessibility upgrades, and it reopened after that work.

Unlike typical monuments, this temple was designed as a functional water processing facility that could handle up to six million gallons daily while serving as an architectural tribute to classical Roman temples.
