Bay seniors with a taste for wildly flamboyant architecture should sign up for a tour of the Haas-Lilienthal House on Franklin Street in the city. It’s SF’s most perfect example of a Queen Anne Style Victorian with a corner tower, wooden gables and a non-stop riot of wooden ornamentation. Built in 1886, it is on the west side of Van Ness so survived the Quake and has been restored, outside and in, to its original excessive glory. Tours are Wednesdays, Saturdays and Sundays and take an hour. Seniors $5.
