Wallfahrtskirche Birnau am Bodensee, Catholic pilgrimage church in Uhldingen-Mühlhofen, Germany.

Wallfahrtskirche Birnau am Bodensee is a rococo pilgrimage church built by Peter Thumb for the Imperial Abbey of Salem, standing above Lake Constance between Nußdorf and Uhldingen-Mühlhofen. Its lake-facing facade has a pale pink ground and white pilasters, with two long wings under steep tiled roofs flanking a central tower crowned by a green copper onion dome and a cross. The tower carries arched windows, a clock and a small balcony above the stepped entrance; a star-shaped stone inlay lies on the paved terrace, with vineyards around.

The present church replaced a pilgrimage chapel at Alt-Birnau, a few kilometres away, whose miraculous Marian statue from around 1420 was moved here. Abbot Anselm II Schwab had Peter Thumb build the new church; the foundation stone was laid on 11 June 1747 and the church was consecrated on 21 September 1750. Salem Abbey was secularised in 1804 and the church closed; Cistercians from Wettingen-Mehrerau bought it in 1919, and Paul VI raised it to a minor basilica in 1971.

The church is dedicated to the Assumption of Mary (15 August) and the Visitation (2 July). The miraculous image, a Marian statue from the Salzkammergut region installed around 1420, now stands at the centre of the interior programme. The Honigschlecker, a putto with a beehive by Joseph Anton Feuchtmayer, sits on the side altar of Saint Bernard.

The church is open daily and allows visitors to walk freely through the main hall and see the altars up close. It is best to plan your visit outside of Mass times to avoid disruptions and have a quieter experience.

Inside the church stands the Honigschlecker, a carved cherub figure holding a honeycomb, which is an unusual and whimsical detail of the baroque decoration. This small sculpture often becomes a favorite discovery for visitors who enjoy finding hidden artistic details.
