About Churchill Downs
Churchill Downs, in Louisville, Kentucky, is a horse racing complex for thoroughbreds. Since 1875 the track has staged the annual Kentucky Derby, which opens the Triple Crown, and the Kentucky Oaks. John and Henry Churchill, whose family was prominent locally, had leased 80 acres (32 ha) to Colonel Meriwether Lewis Clark Jr., their nephew, and the track took the family's name when it was formally named in 1883. It covers 147 acres (59 ha), and the dirt oval where the Derby is run measures one mile (1.6 km) around.
A new ownership group took over in 1894 and commissioned the twin spire grandstand in 1895. In 1896 the signature race was shortened to one and a quarter miles (2.0 km), and the Derby winner began to receive a garland of roses. The twin spires above the grandstands are the track's most recognizable architectural feature and a symbol of the Derby. D.X. Murphy & Bro., a Louisville architectural firm, designed them. A renovation from 2001 to 2005, costing $121 million, replaced the clubhouse, added 79 luxury suites and refurbished the spires.
The Kentucky Derby Museum, on the grounds, focuses on the history of the Derby and Churchill Downs. The Derby is held on the first Saturday in May, with the Kentucky Oaks on the Friday before. Roughly 170,000 people can attend when the infield is open for the Derby. The track became a National Historic Landmark in 1986.
