Mariä Himmelfahrt, Church building in Kemnath, Tirschenreuth district, Bavaria

Mariä Himmelfahrt is a late Gothic hall church in Kemnath, its three aisles covered by vaults. A square tower with a passageway through it adjoins the southeast side; at 58 metres it is the town's tallest structure and closes the east end of the Stadtplatz. The high altar, installed in 1644, shows the Assumption in a painting made in 1859 by two local painters.

A religious site has stood on this location since 1259, but the current building was constructed in 1448 in the late Gothic style. The church survived major challenges including a fire in 1572 and the Reformation, yet was renewed with new altars and artworks between 1650 and 1700 following the Thirty Years War.

The church is dedicated to the Assumption of Mary, celebrated on 15 August. Its two side altars in the chancel date from 1650 and are dedicated to Saint Sebastian and Saint Lawrence; the Sebastian altarpiece is a copy after the Jesuit church of St Michael in Munich. The high altar was consecrated in 1690 by Regensburg auxiliary bishop Albert Ernst von Wartenberg.

The 58-metre tower with its arched gateway forms the eastern end of Kemnath's town square, so the church is reached on foot from the market centre. The tower once served as the town's watchtower. Visitors enter through the portals on the south side; the left portal carries the year 1448 carved outside.

Under the high altar's mensa, a glass shrine holds a relic of the catacomb saint Primianus, handed to the Kemnath parish priest for veneration on 27 August 1692. The high altar itself arrived in 1644 and was consecrated in 1690 by Regensburg auxiliary bishop Albert Ernst von Wartenberg.
