Crystal Ballroom, Historic dance venue in Portland, United States

The Crystal Ballroom sits inside a three-story brick building with high ceilings and large windows from the early 20th century. The main hall extends across a large area with a raised stage at one end and balconies along both sides.

The building opened in 1914 and served as a dance hall and event space across the decades. After renovation in the 1990s, the hall resumed activity as a concert venue.

The building opened in 1914 as Ringler's Cotillion Hall and took its present name in the 1960s under owner Ralph Farrier. The Crystal Hotel next door names its fifty-one rooms after songs and performances from the hall's history and hosts pre- and post-show concerts with the Ballroom.

The ballroom occupies the third floor of the building on Burnside Street, reached by stairs or elevator. The room holds up to 1,000 people for group meetings, or 1,500 standing or 850 seated for concerts. The nearby Crystal Hotel, with 51 guest rooms named after songs or performances from the ballroom's history, hosts pre- and post-show concerts.

The spring-mounted dance floor from the 1920s moves slightly with every step and gives dancers a floating feeling. This construction with ball bearings beneath the wooden panels is rare in North America.
