Church of Holy Trinity, Roman Catholic church in Mešno, Czech Republic

The Church of the Holy Trinity is a single-nave building of white brick in a purist Neo-Gothic style, designed by Arnošt Živný and completed in 1902. It has a rectangular nave with a wooden coffered ceiling, a narrower polygonal presbytery with rib vaulting, a square west tower, a sacristy and a chapel. Three stained-glass windows of 1863 by Jan Zachariáš Quast, showing Charles IV and Elizabeth of Pomerania, came from St Vitus Cathedral.

A Gothic church existed in Mešno by the 14th century, first documented in 1352 when Bohuslav of Švamberk held patronage rights. It was rebuilt in Baroque style in 1737 or 1738, burned down in 1898, and demolished. The present Neo-Gothic church, designed by Arnošt Živný, was consecrated on 9 November 1902 by Cardinal Lev Skrbenský.

The church is dedicated to the Holy Trinity and belongs to the Roman Catholic Church. Its three stained-glass windows, painted in 1863 by Jan Zachariáš Quast for the Imperial Chapel of St Vitus Cathedral in Prague, show Emperor Charles IV and his wife Elizabeth of Pomerania; they were moved here in 1901.

The church stands near the northwestern edge of Mešno on level ground that once served as the village cemetery, with a steeper slope rising to the south. A surviving segment of the old boundary wall on the south side holds a protected sandstone conciliation cross. The square stair annex between the tower's south side and the nave's west wall gives access to the tower.

The church's three stained-glass windows were painted in 1863 by Jan Zachariáš Quast for the Imperial Chapel of St Vitus Cathedral in Prague. They show Emperor Charles IV and his wife Elizabeth of Pomerania, and were removed from the cathedral in 1901 and moved to Mešno.
