St. Laurentius, Catholic parish church in Altmühldorf, Mühldorf am Inn, Bavaria, Germany

St. Laurentius is a late Gothic hall church built of unplastered brick between 1509 and 1518, standing on the high bank west of Mühldorf am Inn. Its west tower, dated 1518 on the first upper floor, carries a steep pointed spire with two arched openings and two clock faces. The nave has a net vault over the central aisle and cross vaults on round pillars; the choir was rebuilt in 1758 in plain Baroque forms.

The building was constructed between 1509 and 1518 during the late Gothic period. Original wall and ceiling paintings from 1759 depict the story of Saint Laurentius, while stained glass windows from around 1510 show saints like Florian, Sebastian, and George.

The church's name day of Saint Lawrence, 10 August, ties the building to the harvest calendar of the Inn valley. The Totenkapelle holds a death altar of around 1700, and the double-decker west gallery built in 1763 separated the congregation by rank. The late Gothic winged altar came from Westerndorf near Rosenheim and was brought here, not made for this church.

The church stands on the high bank west of Mühldorf, above the Inn valley, in the old street village of Altmühldorf. It was closed from November 2016 to May 2019 for plaster and roof-truss repairs after moisture damage from an unsuitable heating system; the altar was consecrated again on 5 May 2019. The west gallery, added in 1763, had long been unusable because of structural problems.

A large altar painting from around 1410 displays the style of Italian and Bohemian artists, depicting Jesus on the cross surrounded by figures in mourning. This rare piece offers visitors a direct window into late medieval religious art that often goes unnoticed.
