Johanneskirche, Gothic Revival church in Erbach, Germany.

The Johanneskirche is a three-aisle hall church in Gothic Revival style, built of rendered brick with sandstone and terracotta detailing. A square tower with a pointed spire projects from the south facade, and a 5/8 choir closes the north end. The slate-covered saddle roof sits above tall pointed-arch windows with tracery.

The church was built between 1861 and 1865 at the request of Princess Marianne von Oranien-Nassau as a memorial to her son Johann Wilhelm. The construction followed the Gothic Revival style that was widely popular in German architecture during that era.

The church is named after the Apostle John and also commemorates Johann Wilhelm, the son of the founder. The organ, built in 1863 by Christian Friedrich Voigt, has 18 registers and was restored to its original state in 2007. The church is a popular venue for weddings, concerts and lectures.

The church is an active parish church, so visits are best timed outside Sunday services. The south portal is the main entrance, and the crypt beneath the altar, which holds Johann Wilhelm's sarcophagus, can be visited on request. The organ gallery and the 1890s choir windows are inside; the building is not fully barrier-free.

The church kept its name only from 1978: 115 years after the 1863 laying of the foundation stone it was named Johanneskirche, honouring both the Apostle John and Marianne's son Johann Wilhelm. His grey Lahn marble sarcophagus in the crypt bears a small angel carved in the workshop of Dutch sculptor Johan Hendrik Stöver, who also made the figures of Faith, Love and Hope behind the altar.
