Church of Saint Giles, Romanesque church in Komárov, Czech Republic.

The Church of Saint Giles in Komárov is a Romanesque structure whose nave was vaulted in Baroque style after the Thirty Years' War, when the present large windows were cut. A single Romanesque window survives in the north wall, and the tower dates from the late 18th century.

This church was built in the 12th century and ranks among the oldest still-active religious buildings in the Brno region. It has undergone changes over time but has kept its basic medieval character.

From the Baroque era, pilgrims set out from the Komárov meadow for Mariazell, and parishioners gathered here in prayer while they were away. On St Giles's Day they welcomed the returning pilgrims with bread and cakes in the so-called "Koláčový svátek" (Cake Feast); Emperor Franz II and his wife attended it in 1834, and it was revived in altered form in 1996.

The church stands on Černovická Street in Komárov, in the Brno-jih district. The Christmas crib is set up during the holidays on the left side of the presbytery in the main nave and, besides services, is open on 25 December and 1 January from 14:00 to 18:00.

The residential tower added to the west facade before 1220 was built by the Benedictines, and the monastery itself bore the name Porta Dei, Gate of God. Its remains were found near the church by archaeologists from the Brno City Museum led by Dana Cejnková.
