One of the most haunted houses in the U.S. (According to the Travel Channel's America's Most Haunted, the house is the number one), the Whaley House was built on part of a cemetery in San Diego, California.  Thomas Whaley built the house in 1857, and is now a museum through years of renovation.   About 120,000 people visit the house annually including stars such as Tom Green and Hugh Hefner.  What brings people here are the stories of ghosts haunting the historic location.  The grounds which the house stands were used for public hangings prior to Mr. Whaley's purchase of the property, including the most famous hanging of Yankee Jim Robinson on September 18, 1852.  Yankee Jim supposedly still haunts the house today, along with the spirit of Violet Whaley (daughter of the Whaley's), who committed suicide there in 1885.  Mr. & Ms. Whaley, and their great-granddaughter (who died tragically in 1912) are believed to haunt the house as well.  Visitors reports seeing the spirits, odd smells (such as cigar smoke which Mr. Whaley's used, and other paranormal anomalies here.
