St. Johannes der Täufer, Catholic church in Obergrainau, Germany

St. Johannes der Täufer is a white Catholic church in Obergrainau, part of Grainau. Its square tower carries a clock face with Roman numerals and is crowned by a dark onion dome with a cross; a smaller onion dome sits at the left end of the steep dark roof. A low wall encloses the churchyard with rows of dark wooden crosses.

Built in 1697 as a Baroque chapel, the building burned on 12 March 1779, losing its altar, furnishings, wooden tower and roof. Franz Seraph Zwinck of Oberammergau finished repainting the interior in 1782, the year it was reconsecrated. It was extended north in 1848/49 and rebuilt in its present form by Carl Sattler between 1925 and 1927.

The 1929 interior paintings form a cycle on John the Baptist by Johann Michael Schmitt. Two scenes are set in local terrain: "Mariens Gang durch das Gebirge" places Mary before the Waxenstein peaks, and the Baptism of Jesus is moved to the shore of the Eibsee. The church is dedicated to John the Baptist, consecrated in his honour on 18 June 1749.

The building is maintained by the Zugspitze parish association. The church sits on a hill above Obergrainau and is easily visible from the main road.

The building is listed as a Bavarian heritage monument and is also protected as an archaeological site due to early modern findings. This dual protection status is uncommon and reflects the long settlement history of the location.
