Origin and history

The church of St Ulrich, located in Altenstadt (a municipality associated with Wissembourg, Bas-Rhin), is an 11th century Romanesque building, partially rebuilt in the 12th century. The first church, erected around 1050, was built before 1130 and completed in the third quarter of the 12th, with an elevated nave. A northern chapel was added around 1220, while the western gate, coming from the collegiate Saint-Étienne destroyed in 1525, was integrated after the Peasants' War.

The church suffered major damage in 1525 during the Peasants' War, requiring repairs: opening windows in the lower side, building a southern chapel, and replacing the gate. In 1708, his cemetery was fortified to serve as a bastion during the Spanish Succession War. The building, with a basilical plan, preserves a five-span Romanesque nave, octagonal pillars, and a carved lintel decorated with symbolic medallions (agnes, plant motifs).

Ranked a historic monument in 1898, the church blends Romanesque elements (dark frieze peg tower, carpented nave) and Gothic or modern additions (dogive vaulted north chapel, apsids rebuilt in the 19th century). The successive restorations (1878-1879, 1903-1906, 1955-1958) preserved its medieval character, such as the four-sided arrow of the tower or the windows of the central ship restored in their original dimension. The pink sandstone, ubiquitous outside, and the decorative sizes of the 11th-XIIth centuries underline its architectural heritage.

The lintel of the Western portal bears a Latin inscription mentioning Abbé Liuthard, suggesting his role in the construction or blessing of the building. The tasker marks (letters A and H) on the double arch of the choir, added in the 18th century, testify to the techniques of the period. The foundations of the tower, reinforced at the beginning of the twentieth century, illustrate the conservation challenges of a monument aged by conflict and time.

Today, the church of Saint Ulrich remains a testament to the Alsatian architectural evolutions, from Romanesque origins to Gothic and Baroque adaptations, to the reparations linked to the wars (1470, 1525, 18th century). Its early ranking (1898) reflects its heritage importance in the religious and historical landscape of Lower Rhine.
