The Pearl District is an area of Portland, Oregon, formerly occupied by warehouses, light industry and railroad classification yards and now noted for its art galleries, upscale businesses and residences. The area has been undergoing significant urban renewal since the mid-1980s when it was reclassified as mixed use from industrial, including the arrival of artists, the removal of a viaduct and construction of the Portland Streetcar. It now mostly consists of high-rise condominiums and warehouse-to-loft conversions.
