Holy Trinity church in Valeč, Baroque church in Valeč, Czech Republic

The Holy Trinity Church in Valeč is a baroque castle church built in 1722–1728 to a design by the Italian architect Giovanni Antonio Biana Rossa, who worked in Valeč from 1701 to 1732. It stands on levelled ground at the western edge of the village, near the castle park and the road to Vrbice. A classicist entrance portico to the crypt was added to the presbytery wall in 1840.

This church was built in the early 18th century when baroque style shaped architecture across Bohemia and Catholic influence guided religious building. Giovanni Antonio Biana Rossa created the design during a period when faith and artistic expression merged in architectural projects.

The church was a pilgrimage site after 1731, but the pilgrimages were abolished under Emperor Joseph II's church reforms. In front of it stands a Holy Trinity column carved by Matyáš Bernard Braun after a design by František Maxmilián Kaňka, installed in 1730.

The church stands on the western edge of Valeč by the road to Vrbice, next to the castle park. It was restored in 2009–2011 and reopened on 7 October 2011. The sources give no opening times or visitor rules, so check locally before planning a look inside.

The church owes its present look partly to a 2009–2011 restoration costing 17.1 million crowns, covered by a grant from the Norwegian Funds; the repaired church was reopened on 7 October 2011. The same work also restored the Holy Trinity column standing in front of it.
