Autobahnkapelle Exter, Protestant highway chapel in Vlotho, Germany

The Autobahnkapelle Exter is a white-plastered church with a long nave under a dark tiled roof and a square west tower topped by a steep pyramidal roof and weather vane. The tower has a small arched window, a doorway and a plaque with the monogram of Elector Friedrich Wilhelm and the year 1666. Inside, a coffered ceiling with stars covers a nave with grey pews, a red aisle carpet, a simple altar, a dark wooden pulpit and a round stained-glass window.

A parish was founded in Exter in 1666 and its first church built; only the massive west tower survives, erected about ten years after the founding and bearing a stone with the monogram of Elector Friedrich Wilhelm and the year 1666. The timber-framed nave was demolished as unsafe in 1951 and replaced by a stone building. In May 1959 the church, beside the A2 junction 31 "Vlotho-West", was consecrated as Germany's first Protestant motorway church.

The church is the oldest Protestant motorway church in Germany, consecrated in May 1959 near the A2 junction Vlotho-West. An Armenian cross stone stands in the tower entrance, donated by a local Armenian refugee family and inaugurated on 2 May 2008; it also commemorates road-traffic victims on this stretch of the A2.

The chapel stands near exit 31 (Vlotho-West) of the A2 motorway. A small rest area with toilets in the adjacent parish hall, renovated in 2007, serves visitors; the tower entrance is at the west side. The A2 section around the chapel is considered one of its most dangerous, so take care when crossing from the parking area.

The Armenian cross-stone in the tower entrance was donated by a local Armenian refugee family in thanks for their welcome, dedicated on 2 May 2008. It also serves as a memorial for road-traffic victims, especially on the A2 stretch by the chapel, considered one of the motorway's most dangerous sections.
