The Marin County Civic Center, designed by Frank Lloyd Wright, is being promoted by the Frank Lloyd Wright Building Conservancy for a nomination to the UNESCO World Heritage List. Why is this interesting? Because it would place the building we drearily enter to pay our speeding tickets alongside such world-renowned sites as the Taj Mahal and the Pyramids of Giza! Conservancy vice-president, author and director of Fallingwater Lynda Waggoner appears this Saturday to talk about the historic significance of the Marin Center and the nomination process; the one-hour lecture is followed by a reception with board members and Frank Lloyd Wright homeowners on Saturday, June 5, at the Marin Center. Board Room 329, 3501 Civic Center Drive, San Rafael. 11am. $10. 415.499.6800.
