Wallfahrtskirche Allerheiligen, Pilgrimage church in Warngau, Germany.

Wallfahrtskirche Allerheiligen is a baroque pilgrimage church in Warngau, about one kilometre south of Oberwarngau. The plastered walls are pale grey and white, with a tall square tower on the left topped by a dark onion dome and a finial cross. The nave and lower side aisle have steep red-tiled roofs; the side wall has tall round-arched windows and smaller rectangular windows below the roofline.

The church was first mentioned in a 1476 document from Tegernsee Monastery, and two earlier buildings from the 15th and 16th centuries are known. The present structure was given its baroque form in the mid-18th century. The last renovation ran from 1983 to 1989.

The church holds many votive plaques left by pilgrims, telling stories of personal prayers answered and promises kept. These plaques reveal how much this place has meant to faithful visitors across the centuries.

The church is open to visitors and serves as a destination for hiking routes in the area. Check ahead about service times and special events, as these may affect access to the building.

The Leonhardifahrt was revived on 23 October 1983 after a break of more than 80 years; it now takes place each year on the fourth Sunday in October, with drivers and riders from the surrounding villages. The church also served as the mortuary for the 41 victims of the Warngau railway accident on 8 June 1975.
