ARCHITECTURE AND THE CITY 2008: Design for Community

AIA San Francisco and the Center for Architecture + Design are pleased to announce the
5th Annual Architecture and the City festival, the nation’s largest architectural event showcasing tours, films, exhibitions, lectures, green programming and more. Devoted to celebrating San Francisco’s unique built environment and design community, the month long festival takes place September 1-30, 2008 and gives participants the opportunity to engage in conversation about our city.

Last year, more than 20,000 people, from all over the world, took part in the festivities. With your support, we look forward to making the 2008 festival another highly successful, city-wide venture. Mayor Gavin Newsom has once again officially proclaimed September “Architecture and the City” month.
