The Gaslamp Quarter is a 16½ block historical neighborhood in downtown San Diego, California. The area is listed as a historic district on the National Register of Historic Places as Gaslamp Quarter Historic District. Its main period of development began in 1867, when Alonzo Horton bought the land in hopes of creating a new city center closer to the bay, and chose 5th Avenue as its main street. After a period of urban decay, the neighborhood underwent urban renewal in the 1980s and 1990s, and is today an energetic business and entertainment district.
The Quarter is home to many events and festivals, including Mardi Gras in the Gaslamp, Street Scene Music Festival, Taste of Gaslamp and ShamROCK, a St. Patrick's Day event. PETCO Park, home of the San Diego Padres is located one block away in downtown San Diego's East Village. The Gaslamp Quarter, which is listed on the National Register of Historic Places, extends from Broadway to Harbor Drive, and from 4th to 6th Avenue, covering 16½ blocks. It includes 94 historic buildings, most of which were constructed in the Victorian Era, and are still in use with active tenants including restaurants, shops and nightclubs.
