Congress Center derives its name from the distinguished Congress Hotel, built in 1912 and formerly located on the site.  Awarded the Certificate of Merit by the Portland Historical Landmarks Commission, Congress Center possesses remnants from the original structure and a gazebo was constructed replicating the historic arches that framed the former hotel’s entrance.  The hexagon-shaped tower is clad in charcoal gray reflective glass, with Spanish pink granite at the two-story ground level.  The building features a two-story lobby with granite walls and glass trim, limestone/sandstone floors, and Anigre wood walls that curve into the ground-level retail shops.  The property’s upper floors offer scenic views of the Willamette River and snow-capped Mount Hood and Mount St. Helens, and views of the west hills and cityscape can be enjoyed from all floors. 

Congress Center is ideally located in Portland’s central business district bounded by SW 5th and 6th Avenues, and Salmon and Main Streets.  The building is central to the heart of the city and all its conveniences, from government offices to transportation, hotels, restaurants, shopping and entertainment centers.
