The spires of glass that reach up and pierce the Portland skyline are a testimony to this city's appreciation of both art and function in the architectural styles gracing the downtown and waterfront areas. The Convention Center offers more than 500,000 square feet for accommodating meetings, banquets, exhibits, fairs or shows. During the annual Rose Festival, throngs of excited extroverts from all around the world gather at the OCC to view the floats made from millions of flowers—which tour the city every June in the Grand Floral Parade.
