A New York entrepreneur, Thomas Whaley came to California during the gold rush. He wanted to provide his East Coast wife with all the comforts of home, so in 1857 he had Southern California's first two-story brick structure built, making it the oldest double-story brick building on the West Coast. The house, which served as the county courthouse and government seat during the 1870s, stands in strong contrast to the Spanish-style adobe residences that surround the nearby
historic plaza and marks an early stage of San Diego's "Americanization." A garden out back includes many varieties of prehybrid roses from before 1867. The place is perhaps most famed, however, for the ghosts that are said to inhabit it. You can tour on your own during the day, but must visit by guided tour starting at 5 pm. The evening tours are geared toward the supernatural aspects of the house. They are offered every half hour, with the last tour departing at 9:30 pm, and last about 45 minutes.
