Mariä Himmelfahrt, neoclassical church in Bad Neustadt an der Saale, Germany

Mariä Himmelfahrt is a neoclassical basilica: a plain exterior with a 56-metre tower over the main entrance, and inside three naves where 11-metre Corinthian columns carry a barrel vault, the side aisles flat-ceilinged. The round choir is set off by a circle of columns and a dome-like ceiling. The building is 49.77 m long outside and 21 m wide, with walls 1.30 m thick.

A Romanesque church with a choir tower stood here from about 1050; it was rebuilt in Gothic style in 1352, and its foundations, uncovered in 1983/84, are marked in the paving at the northeast corner. The church was demolished in 1793 for structural defects and lack of space. Plans by Alois Geigel were carried out after his death by court architect Andreas Gärtner, interrupted by money shortages and the Napoleonic wars, and finished in 1834 with help from King Ludwig I of Bavaria. Johann Philipp Mattlener designed the interior, and the church was consecrated on 10 August 1836.

The parish is named for the Assumption of Mary (Mariä Himmelfahrt) and belongs to the Diocese of Würzburg's Bad Neustadt deanery. Four bells hang in the tower; the Friedensglocke was cast in 1648, the year the Thirty Years' War ended, and the smallest bell was donated by Josef and Elisabeth Englert of Sommerau in the Spessart.

The main entrance lies under the 56-metre east tower, whose square plan measures eight metres a side; the interior is entered from this east end, so the altar appears at the far west. The building is 49.77 metres long outside and 21 metres wide, with walls 1.30 metres thick. The floor plan is turned about 30 degrees from that of its predecessors, and paving at the northeast corner marks the foundations of the 1352 Gothic church.

The church is rotated about 30 degrees from its predecessors and its altar stands at the west end. The east tower over the main entrance is eight metres square and rises 56 metres to the tip of the cross. Inside, the round choir is set apart by a circle of columns and a dome-like ceiling.
