Church of Holy Trinity, church building in Srní, Czech Republic

The Church of the Holy Trinity in Srní is a single-nave stone building with a prismatic tower set off-axis from the nave. The tower has an onion-shaped roof, the three-sided presbytery is vaulted with a barrel vault, and the south windward side is clad in shingles. Inside are a Baroque altar and Rococo candlesticks from the church's early years.

The wooden church, permitted by Emperor Joseph II, was built in 1788 by the villages of Sedlo and Srní and consecrated on 10 August 1789. It was replaced by a stone church funded partly by Emperor Francis I with 5,443 guilders and 39 kreuzers, consecrated on 15 August 1806 by Bishop Jan Prokop Schaaffgotsche. In 1916 two large bells were removed for military use; replacements by Rudolf Perner of České Budějovice were hung in 1922.

The church is the former parish church of Srní, a parish established in 1803 and dissolved on 31 December 2019, after which it became a filial church of Kašperské Hory. Mass is held once a month. In 2013 the pilgrimage celebration to Our Lady of Hauswald was revived; it takes place in mid-August, with a procession coming to the church from the Hauswald chapel.

The church stands in the centre of Srní inside Šumava National Park, with its tower set off the axis of the single nave and a shingled south side facing the weather. Mass is held once a month, so check the parish notice before travelling. The former cemetery, abolished in 1984, is now a memorial park with a Stole of Reconciliation and a plaque.

The main altar is decorated with beads made at the Antýgl glassworks. The wooden statue of Our Lady of Lourdes on the side altar comes from the Hauswald pilgrimage chapel, which was demolished by blasting in 1957. A cannonball from the Napoleonic Wars, brought by pastor Wenzel Prinz from the battlefield at Teplice, was walled into the gate of the former parish house built in 1820.
