All the interior walls on the first floor of the tower are decorated with murals. In what is now the gift shop, there is an interesting row of painted "plaques" high up on the walls naming the murals and the artist who created each one. Also given are the dimensions of each mural and the technique used to create it. Pictured here is the painted plaque for Edward Terada's Sports, a fresco measuring nine feet by ten feet, we are told. The tower was built in 1933, the mural painting project completed by 1934. Apparently there are more murals in the stairwell, not normally open to the public, except during docent-led tours (see below). The mural project was sponsored by the Public Works of Art Project (PWAP), a New Deal program aimed at supporting artists—artists who in this case included: Maxine Albro, Victor Arnautoff, Jane Berlandina, Ray Bertrand, Ray Boynton, Rinaldo Cuneo, Hebe Daum, Mallette Harold Dean, Edith Hamlin, George Albert Harris, Otis Oldfield, Frederick E. Olmsted Jr., José Moya del Piño, Suzanne Scheuer, Ralph Stackpole, Edward Terada, Clifford Wight, Frede Vidar, and Bernhard Zakheim. PWAP was a WPA precursor.
fanciful underwater murals from the same period (completed in 1939) by Hilaire Hiler (1898-1966) at the former oceanside bathhouse at the end of Polk St., now part of the San Francisco Maritime Museum—another government-sponsored, depression-era arts project. Both are well worth a visit. Note that parking is extremely limited at Coit Tower. It's probably best to go in the winter months and on a weekday, if possible. For information about visiting Coit Tower and docent-led tours, visit the official Coit Tower website.
