Church of Saint John the Baptist in Manětín, Baroque church in Manětín, Czech Republic.

The Church of Saint John the Baptist in Manětín is a Baroque building with vaulted ceilings and ornately decorated interior walls. The structure displays characteristic features of this architectural period with detailed ornamentation throughout its interior.

Manětín and its church are first mentioned in 1182 as property of the Knights Hospitaller, whose commandery is documented in 1325 and who held the town until 1483, when the Švamberks acquired it. Gothic masonry survives in the presbytery. After a fire destroyed half the town and the church in 1712, Václav Josef Lažanský and his wife Marie Gabriela had a new church built in 1712–1717, probably to a design by Thomas Haffenecker, supervised by Jan Jiří Hess and consecrated in 1717.

The church is dedicated to Saint John the Baptist and was consecrated on his feast day in 1717 by Prague auxiliary bishop Daniel Josef Mayer. Its parish was raised to a deanery in 1729, and the church then oversaw several surrounding villages. Dean František Wonka served here from 1925 to 1967 and researched the Manětín Baroque.

The church stands on the square in Manětín, its tower on the north side of the nave and the lord's oratory on the south, joined to the castle by a covered corridor over the lane. The former cemetery survives only as a boundary wall. The building is an active place of worship, so check opening times before visiting.

The church attic shelters the largest colony of greater mouse-eared bats in the Plzeň Region, declared a European Important Site in 2009. At the time of designation it held around a thousand individuals, about 600 females and young, while the region's second-largest colony, at the Church of the Holy Spirit in Všeruby, numbered only about 150.
