Ehemalige Hospitalkapelle St. Wendelin, Gothic chapel in Butzbach, Germany.

The Ehemalige Hospitalkapelle St. Wendelin is a former hospital chapel in Butzbach, built around 1440 and considered the oldest timber-framed church in Hesse. Its white half-timbered walls with red-brown beams support a steep slate roof topped by a slender octagonal spire on a small square tower. Tall, narrow windows with multiple panes light the interior, which holds a carved altar from the early 16th century.

The chapel originated in the Middle Ages as part of a hospital that served the sick and poor. This role as a place of prayer and care shaped the building over many centuries.

The chapel shows how the community cared for the sick and poor, and what role faith played in that work. The building tells of the church's responsibility for social welfare during medieval times.

The building is visible from outside and can be visited depending on opening times, which may change regularly. Visitors should check ahead to see if access is possible on their planned day.

Archaeological digs between 1 October 1980 and 5 December 1981 found three floor levels and 0.80-metre basalt foundations of a 13th-century stone chapel beneath the present east end. Below them lay a post hole, a dark brown layer and a 6–7 cm peat layer, read as the floor of a wooden building of about the 10th century on the old Roman road.
