Evangelische Kirche Blankenstein, Protestant church in Blankenstein, Hattingen, Germany.

Evangelische Kirche Blankenstein is an 18th-century Protestant church built probably in 1767, as a date above the tower entrance suggests, with the tower added in 1775. It stands by the bridge between the outer and main castle of Blankenstein. The nave has a dark slate roof, and the lower polygonal apse of rough light brown stone blocks is pierced by a tall, narrow round-arched window with two vertical mullions. A steep slate spire with four triangular gables tops the square stone tower, which has a single small round-arched window. An old entrance is visible on the south side of the nave.

Lutheran teaching was introduced in Blankenstein during the tenure of castle chaplain Wilhelm Steintgen, 1527 to 1540. On 16 August 1607 Duke Johann Wilhelm I granted the Protestant community permission to separate from the St. Georg parish in Hattingen. The present church was probably built in 1767, as a date above the tower entrance suggests; the tower followed in 1775. Renovation took place in 1973–1974, and since 2006 the congregation has collected funds for further repairs.

The pulpit altar reflects Baroque traditions of Protestant worship that continue to shape how the community gathers. The baptismal font from 1689 remains an important focus for religious ceremonies held here.

The church is located in the Blankenstein district and is easily visible from the street, with straightforward access to the building. Services and private events happen regularly here, so checking opening times before visiting helps you avoid disruptions.

The three cast-steel bells, tuned to g', b' and c'', were cast in 1917, during the First World War, when bell metal was scarce and steel founders took over the work. They hang in the tower built in 1775, whose entrance carries the year 1767 above it.
