Designed by Willis Polk and built in 1908, the former Crocker Bank Headquarters (now Wells Fargo) has one of the city's most lavish interiors, with rows of white-marble columns beneath a coffered ceiling ornamented with rosettes. Hunched gargoyles support marble check-writing tables with inkwells cradled by winged statuettes. No photos, lest the guards pounce. The roof is a public garden.
