Loket Castle (Czech: Hrad Loket, German: Burg Elbogen) is a 12th-century Gothic castle in Loket in the Karlovy Vary Region of the Czech Republic. It ls located on a massive rock, surrounded on three sides by the Ohře river. Once known as "the Impregnable Castle of Bohemia", because of its thick walls, it is one of the oldest stone castles in the country. It is administered by the Loket Castle Foundation since 1993 and preserved today as a museum and national monument. First built in the Romanesque style in the 12th century, the castle was expanded in the Gothic style during the next century, and took most of its current form during reconstruction work in the 1390s.
