The Loket castle, built of stone, is more than 800 year old settlement, positioned on a granite rock that is runaround by the river of Ohre. It was most probably founded as a frontier fortress. The castle served to kings, Lords of Schlick and Lords of Plauen, Loket´s townsmen and it was used as prison in 19th and 20th century. Shortly after 1989, it was open for public.
