Johanneskirche, Protestant church in Heidelberg, Germany

Johanneskirche is a Protestant church built 1899–1902 in Heidelberg's Neuenheim district, designed by Hermann Behaghel in a style drawing on early Burgundian Gothic. Unlike a Gothic basilica it is a central building on a Greek cross plan, its southern arm walled off as a confirmation hall. It stands free at a street fork, so the facade is worked on three sides, with the 55 m tower rising above the north main entrance.

Neuenheim's rapid growth after its 1891 incorporation into Heidelberg made the old church on the Marktplatz too small; a planned 1895 extension was abandoned in favour of a new building outside the village core. The foundation stone was laid in 1900 at a bend in the Handschuhsheimer Landstraße, and Grand Duke Friedrich I attended the consecration on 11 May 1902. The design was the first Heidelberg church by Hermann Behaghel, later responsible for the Christuskirche, Kreuzkirche and Friedenskirche.

The name passed from the old village church to the new building but changed referent: it now honours John the Evangelist rather than John the Baptist. Inside, the Wiesbaden Programme places pulpit and font flanking the altar, with the organ above it, and galleries run around all sides for the sermon-centred service.

The church stands free at a fork where the Handschuhsheimer Landstraße bends, so its facade is designed to be seen from three sides; the main entrance is on the north side, beneath the 55 m tower. The southern arm behind the altar is separated off as a confirmation room. It is an active Protestant parish church, so time a visit outside services.

The church is a central building on a Greek cross plan, not a longitudinal Gothic nave; the south arm behind the altar is walled off as a confirmation hall. Because it stands free at a street fork, its facade is finished on three sides, with the 55-metre tower rising over the north main entrance.
