Westlake Center is a four-story shopping center and twenty-five story office tower in Downtown Seattle, Washington, USA. The southern terminus of the Seattle Center Monorail, it is located across Pine Street from Westlake Park, between 4th and 5th Avenues. It is named for Westlake Avenue, which now terminates north of the mall but once ran two blocks farther south to Pike Street. Westlake Park is considered Seattle's "town square" and celebrities and political figures often make appearances or give speeches from the building's balcony.
The structure was designed by RTKL Associats on 11,000 square meters. Opened in 1988 by The Rouse Company, since 2004 it has been owned by Real Estate Investment Trust General Growth Properties.
