Castle Bor, Gothic château in Bor u Tachova, Czech Republic

Castle Bor is a Gothic château in Bor u Tachova featuring a distinctive cylindrical tower as its central element. The building combines medieval structures with later additions from the 19th century across multiple connected sections.

The castle was first mentioned in 1263, founded by Ratmír, burgrave of Přimda, and his son Bohuslav, who styled himself "of Bor" from 1285. The Švamberk family held it until 1650; Jan of Švamberk had the decayed castle rebuilt in late Gothic style, and in 1430 Hussites besieged it unsuccessfully. A 1454 deed calls it deserted, and the present neo-Gothic form dates from the late 19th century.

The village of Bor was raised to the rank of a small town in 1369 by Bohuslav I of Švamberk, and the castle chapel of St Lawrence, founded before 1362, survives in the east wing. In the entrance hall stands a figural tombstone, probably of a daughter of Jan of Švamberk (died 1533).

The château stands at Plzeňská ulice 259 in the town of Bor, in the Tachov district. It is a protected cultural monument, so visits focus on the building and its chapel rather than open grounds. The chapel of St Lawrence, in the east wing, holds the palm prints in its Renaissance plaster.

In the chapel wall, visitors can spot the imprints of two palms in the Renaissance plaster, and the entrance hall holds a figural tombstone, likely of the daughter of Jan ze Švamberka († 1533). The castle core also preserves a round bergfrit with walls up to 3.5 m thick.
