Hirsau Abbey was once one of the most important Benedictine abbeys of Germany. In the 11th and 12th century, the monastery was a centre of the Cluniac Reforms, implemented as 'Hirsau Reforms' in the German lands. The complex was devastated during the War of the Palatine Succession in 1692 and not rebuilt.
A Christian chapel at Hirsau dedicated to Saint Nazarius had already been erected in the late 8th century. The monastery itself was founded in about 830 by the Rhenish Franconian count Erlafried of Calw at the instigation of his relative, Bishop Notting of Vercelli, who gave it the relics of Saint Aurelius of Riditio, an Armenian bishop who had died about 475, brought from Milan among other treasures; they were first placed in the oratory of St. Nazarius' Chapel, while the monastery at Hirschau was being built on the count's estates. A first aisleless church, dedicated to Saint Aurelius, was not completed until 838, when it was consecrated by Archbishop Odgar of Mainz, who at the same time translated the relics from their temporary resting place to the new church.
In the 11th century, under Abbot Wilhelm, Hirsau Monastery was part of the Cluny reform movement. From here, the reforms, which emphasised the independence of the Church, spread across much of southwestern Germany. As a loyal supporter of the Pope, Hirsau played an active role in the Investiture Controversy, a power struggle between the Church and European monarchies.
After the Reformation, the former monastery became a Protestant boarding school. In the late 16th century, a Renaissance-style hunting lodge was constructed for the dukes of Württemberg. A grand structure with three wings, the palace abutted onto the enclosed grounds of the monastery, on the site of the former abbot’s residence.
In 1692, while occupied by French soldiers, the palace and monastery was destroyed by fire. In the aftermath, local residents plundered the remains in search of building materials, partly for the reconstruction of the town of Calw, which had been damaged in the war.
Today, the former monastery complex is a beautiful but atmospheric place, with the striking Romanesque and Gothic ruins set against the scenic backdrop of the Black Forest. Rising above the landscape, the 37- metre high Eulenturm (owls’ tower) features a frieze of mysterious figures. The late Gothic Marienkirche (church of St Mary) and an assortment of monastic buildings offer a glimpse into everyday life at an abbey that was once one of the most influential spiritual and economic centres of the region.References:
Frösöstenen is the northern-most raised runestone in the world and Jämtland's only runestone. It originally stood at the tip of ferry terminal on the sound between the island of Frösön and Östersund. The stone dates to between 1030 and 1050. It has now been relocated to the lawn in front of the local county seat due to the construction of a new bridge, between 1969 and 1971, on the original site.
Frösö runestone inscription means: Austmaðr, Guðfastr's son, had this stone raised and this bridge built and Christianized Jämtland. Ásbjörn built the bridge. Trjónn and Steinn carved these runes.
