St. Mariä Geburt, Baroque parish church in Monschau, Germany.

St. Mariä Geburt is a baroque parish church in Monschau, built from 1649 to 1650 as a plain single-nave hall church of rough rubble masonry with three bays and a pitched roof. The south end has a recessed choir and apse under a hipped roof, while a small square bell tower with an octagonal helm and metal cross rises above the north gable. The main entrance is reached by twelve broad steps secured by wrought-iron gates.

The church was built between 1649 and 1650 by Premonstratensians from a nearby monastery. Its construction happened when Monschau separated from the neighboring community to establish itself as an independent parish.

The church is dedicated to the Nativity of Mary and Saint Joseph, and was consecrated on 8 September 1650. Its furnishings came from other religious houses or from donors: the wooden high altar was made in 1780 for the Reichenstein monastery, and the two side altars date from 1650. The left one was given by Martin Bewer, abbot of St. Maximin in Trier; the right holds a figure of the Apostle Matthias.

The church stands on a slope, so the main entrance is reached by twelve broad steps secured with wrought-iron gates; the foundation is higher than the street and held by a massive retaining wall. Inside there are about 130 seats and 100 standing places. Around twenty small stone crosses along the outer eastern walls mark former pastors.

The clock on the entrance side of the tower dates from 1511, predating the church by nearly 140 years. The two bells also came from elsewhere: the smaller one was cast by Josef Beduwe in 1864 and had previously rung in the Aukirche, while the second dates from 1878.
