At first glance this stunning, rosy rococo palace seems to be from another world, and indeed, it's the sole survivor of the many tinted-plaster structures (a temporary classical city of sorts) built for the 1915 Panama-Pacific International Exposition, the world's fair that celebrated San Francisco's recovery from the 1906 earthquake and fire. The expo buildings originally extended about a mile along the shore. Bernard Maybeck designed this faux Roman Classic beauty, which was reconstructed in concrete and reopened in 1967.

A victim of the elements, the palace is currently undergoing a piece-by-piece renovation; stand under the rotunda and look up to see the net that's protecting you from falling debris. The massive columns (each topped with four "weeping maidens"), great rotunda, and swan-filled lagoon have been used in countless fashion layouts, films, and wedding photo shoots. After admiring the lagoon, look across the street to the house at 3460 Baker Street. If the maidens out front look familiar, they should—they're original casts of the lovely "garland ladies" you can see in the Palace's colonnade. The house was on the market in 2007; if you've got a cool $8 million, it could be yours.
