Kloster Murrhardt, Benedictine monastery in Murrhardt, Germany.

Kloster Murrhardt is a former Benedictine abbey in Murrhardt, Baden-Württemberg, founded around 750 as a cell of St. Trinitatis and later dedicated to St. Januarius. Its church site, now the town church, was built over a small wooden church of around 736, of which remains were found in 1963; the monastery also included the Walterichskirche.

Pippin the Younger founded the monastic cell St. Trinitatis around 750; it was renewed in 817 when Louis the Pious established a Benedictine abbey with Abbot Walterich and twelve monks from Reichenau. The abbey existed until 1556 and again from 1635 to 1648, with the heart of Louis the Pious buried in the Januarius altar in 840.

The monastery is no longer a religious community; it was dissolved in 1556 and only briefly revived from 1635 to 1648. Its name lives on in the town's parish church of St. Januarius, which preserves the monastery's patron saint. Visitors can see the Kenotaph of Emperor Louis the Pious, a later memorial marking where his heart was kept until the 16th century.

Visitors can explore the grounds through guided tours that explain the main buildings and their purposes. It is helpful to check opening times and access conditions before planning your visit.

The monastery sits within a network of hiking trails that connect to surrounding forests and hills, showing how the location relates to the natural landscape. This connection to the land was integral to monastic life.
