Loket Castle 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.

Considered to be the second most expensive historical artifact in the Czech territory. The golden chasse with wooden core and remnants of the saint was made in 13th century. It belonged to Belgian family of Beauforts, who brought it here at the end of 19th century. After cooperating with nazis, they were forced to leave in 1945, and that's when they buried the treasure in a church floor. It was forgotten for decades and only found again in 1985, after a "suspicious" request to authorities from an American businessman, who wanted to buy a "thing that nobody would be missing". Later it was restored and nowadays exhibited in the Bečov Castle.
