The historic Town of Georgetown is the Territorial Charter Municipality that is the county seat of Clear Creek County, Colorado, United States.The town population was 1,034 at the 2010 census.
The town was founded in 1859 during the Pike's Peak Gold Rush by George and David Griffith, two prospectors from Kentucky. It was named "Georgetown" in honor of the older of the two brothers. Although founded during the gold rush, the town grew rapidly following the discovery of silver on September 14, 1864, by James Huff at a site approximately 8 miles (13 km) up the canyon in the Argentine Pass area. Georgetown was incorporated on January 10, 1868, and a few months later it wrested the county seat from nearby Idaho Springs, which is a larger community today. The historic courthouse dates from this year. Georgetown is the only Colorado municipality that still operates under a charter from the Territory of Colorado. The building of the narrow gauge Colorado Central Railroad up the canyon from Golden in the 1870s further increased the central position of the town. The historic downtown was used as the location for the filming of a scene from the 1978 movie Every Which Way But Loose starring Clint Eastwood. The scene features the climactic showdown between Philo Beddoe (Eastwood's character) and the Black Widows motorcycle gang. The town was also used in the 1998 film Phantoms which included the historic Hotel de Paris, as well as the colonial-style post office.
