The Pacific Building – 520 S.W. Yamhill Street near 5th Avenue, Portland, Oregon

The Pacific Building is a historic office building (built in 1926) in downtown Portland, Oregon, United States. This building was the second of three similarly-Italianate buildings built in Portland by prolific local architect A.E. Doyle’s firm. The lobby of the 10-story building was designed by Belluschi, and connected to Portland’s first underground parking garage. The connection to the parking garage was lost in 2000 when the former bus station to the south (which sat on top of the garage) was torn down and replaced by an annex to the nearby Hilton Hotel.
Architecturally, the Pacific Building appears to combine the Chicago School with Italian Renaissance architecture. The red tile roof and dormers combine with geometric windows that are almost flush with the facade to achieve this effect.

The lot upon which the Pacific Building stands is across Yamhill Street from Pioneer Courthouse, in the heart of downtown Portland. The entire lot once was the grounds of the Henry Corbett mansion (built 1875), which remained until construction began on the Pacific Building. Corbett’s widow kept a cow on the grounds at one time while a major city grew around it. This juxtapositioning of the old and new earned the lot a nickname: "The Million Dollar Cowpasture"

The Pacific Building has been listed on the National Register of Historic Places since March 5, 1992.
