October 21, 1959. American Trust Company opened a distinctive modern banking space in downtown San Francisco, shortly before American Trust merged with Wells Fargo Bank. Architects Skidmore, Owings & Merrill designed the building in a perfect circle, 70 feet in diameter, and clad in 40-foot glass walls. The spaceship-like interior was light, open, and round. For many years Wells Fargo’s Crown-Zellerbach bank branch was located in this building. Although no longer a bank, this mid-century ultra-modern building was designated a city historical landmark in 1987.
