Evangelische Stadtkirche, Gothic church in Dillenburg, Germany

The Evangelische Stadtkirche is a late Gothic church building on a steep slope of the Dillenberg with a single-nave hall and a western tower. The structure sits on ancient foundations connected to burial sites of noble families from earlier centuries.

The church was built around 1490 and consecrated in 1491, constructed above the burial site of the Counts of Nassau from earlier generations. In the early 1500s, it transformed into a Protestant house of worship.

The church holds the graves of 79 members of the House of Nassau, among them William the Rich (1487–1559), Juliana of Stolberg (1506–1580) and John VI of Nassau-Dillenburg (1536–1606), which draws many Dutch visitors. William of Orange attended the church's inauguration and had his son Maurice baptised here. The tower also carries a bell about 500 years old.

The church stands on the steep slope of the Dillenberg below the former castle site, so the approach from the old town involves a climb. The west tower is built into the nave, while the unplastered stair turret and north porch, both from 1902, stand out from the plastered older walls. The princely box above the south choir crypt is now entered only from inside the church.

The church holds a bell about 500 years old; William of Orange attended its first ringing, and he later had his son Maurice baptised here. The building also sheltered the Latin school founded by John VI of Nassau in its attic for 200 years, the forerunner of today's Wilhelm-von-Oranien-Schule.
