St. Jakob's Church is the main parish church of the lower town, standing just off Stadtplatz beneath the castle cliff. Its high Gothic lines suit Burghausen's vertical drama: tower above roofs, castle above tower, sky above the ridge.
Inside, the church is calmer than the street outside, with late-medieval bones and later furnishings layered together in the Bavarian way. It is a good short stop while exploring Stadtplatz, and it helps explain how the lower town functioned beneath the ducal fortress.
