				Preston Castle
				
				The "Castle", built in 1890-1894, is the most significant example of Romanesque Revival architecture in the Mother Lode. It was built to house the Preston School of Industry, established by the state legislature as a progressive action toward rehabilitating, rather than simply imprisoning, juvenile offenders. Doors of the 120 room "castle" closed in 1960 after new facilities were completed.
