Klosterkirche St. Heinrich, Medieval monastery church in Pirna, Germany.

Klosterkirche St. Heinrich is a two-nave Gothic hall church with stone vaults, decorated walls, and a tower positioned between the nave and choir. The building features tall windows that flood the interior with light and carefully crafted vaults that define the sacred space.

Dominican monks from Leipzig established the monastery around 1300 and expanded it during the 14th century into a major religious center. The church became a place of intense monastic activity within the growing city.

The wall paintings date from the 14th century, not the 15th: the east wall shows the Last Judgment, the south wall a Madonna with donor, and the northwest bay the confirmation of the Dominican order by Pope Innocent IV. The vault paintings with plant motifs were largely renewed in 1956/57.

The church stands at the northwestern edge of Pirna's old town, with the former chapter house, now the Stadtmuseum Pirna, directly to its north. The nave was restored between September 2002 and December 2003 after the Elbe flood, when platforms, benches and heating were renewed. The west wall is completely closed, so entrances are in the second bay from the west, and only the northern one is original.

The high altar's crucifix by Friedrich Press dates from 1973, but the church also keeps a late-Gothic retable of 1510/20 on the south wall, showing the Virgin Mary between Mary Magdalene and Margaret. Its wings carry painted saints, including Leonard and John the Baptist on the outer left side.
