This building in downtown Tucson always catches the attention of tourists due to its pink exterior and eclectic architecture. It was actually built in 1902 according to the design of Chicago architect Louis Sullivan, with geometrical friezes, Sonoran-style drainpipes sticking out underneath the roof, and a facade that imitates the Spanish missions of the Southwest. Formerly the home of the Fraternal Order of Owls (as signified by the sculpted owl looking down on the street from the top level), the building is now a private residence. Your appreciation of the architecture will have to be limited to the outside.
