St. Procopius Church, Parish church in Žďár nad Sázavou, Czech Republic

St. Procopius Church is a Gothic church with two asymmetric naves, 33.5 m long, 17.6 m wide and 10.7 m high, ending in a five-sided octagonal chancel. Its 53 m tower and sacristy stand on the north side beside the chancel, and the west façade has pointed three-part windows with tracery. Two octagonal pillars divide the naves, one with a cross-ribbed vault and the other with a net vault.

A church may have stood here by 1270, but the first reliable record is from 1391, when the priest Svatoslav mentioned the church and its parish. The north nave and present chancel were added in the 15th century, the vaults, entrance hall, sacristy and chapel in the 16th. A lightning strike in 1651 destroyed the roof, which was replaced; the sacristy's star vault followed in the 18th century, and stained glass was installed between 1870 and 1910.

The church's coats of arms, painted on the vault ribs and pillars, recall the founders and patrons of the Žďár monastery: Lichtenburk crossed branches, the Kunštát stripes and the Silesian eagle of the Münsterberk dukes. A quartered shield with a swallow and a bar, linked to Přibyslav of Křižanov and his wife Sibyla, resembles the Gallas arms.

The church stands on a spur above the Sázava River, next to the Tvrze and a short walk from Náměstí Republiky. Its axis is turned markedly to the northeast, and the Baroque Chapel of St. Barbara continues that line beyond the chancel. The tower, 53 m high, rises on the north side beside the sacristy.

The church was built using a longwall system rather than the carcass system common in its period, and the piers of the chancel stop about halfway up the wall instead of reaching the floor. The music gallery at the west end spans both naves on four octagonal pillars.
