Frauenkirche Unterriexingen, Gothic church in Markgröningen, Germany.

Frauenkirche Unterriexingen is a Gothic church situated on a hilltop between the Enz and Glems valleys. The building displays fully restored sections alongside areas that retain their historic ruined appearance, reflecting different phases of its preservation.

The building started in the 13th century as a pilgrimage chapel and underwent significant expansion during the 14th century. It served as the parish church until 1628, when its role shifted.

The name Frauenkirche comes from the dedication to Unserer Lieben Frau (Mary), not from the village. Locals also call the church "s'Käppele". Before the Reformation it drew pilgrims, including a monk from Hungary, and its walls carried frescoes of the Last Judgment. Since its restoration it has hosted funeral services for the parish.

The site is located outside the village center on elevated ground, which should be considered when planning a visit. After extensive renovation work between 1999 and 2003, the church is now accessible in good condition.

The church's interior nave deliberately retains its ruined character from the 19th century, while the tower, roof and gallery were rebuilt in 1874/75. A Romanesque crucifix from the 12th century, brought from the Leutrum family seat at Ertingen in 1891, hangs inside.
