Church of Saint Giles, Baroque church in Líšeň, Czech Republic.

The Church of Saint Giles is an oriented single-nave building with a semicircular presbytery and a prismatic tower on Karla IV Square. The western nave masonry is Romanesque from the second quarter of the 13th century, the tower's lower floors are Gothic, and the nave's second half with presbytery dates from 1895. A Baroque Chapel of the Holy Cross adjoins the north side.

The church's Romanesque core dates to the second quarter of the 13th century, probably founded by Gerhard of Zbraslav and dedicated to Saint Giles. A charter of 23 February 1306 first mentions it as a filial church of Šlapanice. Gothic work in the 14th century produced the tower's lower floors, and a Baroque reconstruction in 1718–1720 by František Benedikt Klíčník added the clock tower and sacristy.

The church is the parish church of the Roman Catholic parish of Brno-Líšeň. Its tower and the small roof turret are topped with double-armed crosses, a reference to the Protestant tradition of the early 17th century that was later replaced by Catholic use. The altar with the miraculous image of Our Lady Help of Christians was moved here after the pilgrimage chapel on Kostelíček hill was demolished after 1784.

The church stands on náměstí Karla IV in Brno-Líšeň, with its tower and clock facing the square. The entrance is through the tower, and the south porch with the upper oratory adjoins the nave. The Chapel of the Holy Cross, added around 1730, opens off the north side of the nave.

The building earned recognition as a cultural monument of the Czech Republic, underscoring its architectural and historical importance. This designation reveals that it holds value beyond the local district for the nation's broader cultural heritage.
