The Old Parish Church of Gries contains several precious works of art. Some parts of the original Romanesque church are still preserved, as parts of the walls of the tower and nave. There has probably been a settlement in the area since Roman times.
The Gothic, polygonal choir was built in 1414. During the course of the 16th century the Romanesque church was rebuilt. Star-shaped vaults were inserted in the nave, and in 1529 a church porch, also with star-shaped vaults, were built. The tower also received its pointed spire at this time. The chapel dedicated to Saint Erasmus was finished already in 1519.
In 1788, the church lost its position as parish church of Gries. The Muri-Gries Abbey from now on instead served this purpose. The church is surrounded by the old cemetery of the Parish, which since 1922 is closed for new graves. Among the people buried here, Austrian admiral and explorer Bernhard von Wüllerstorf-Urbair is among the more well-known.
The old parish church contains two pieces of art of high value. The one is a Romanesque crucifix, dating from circa 1200 and probably made abroad (possibly northern France)
The other is a late Gothic, carved wooden altarpiece made by Michael Pacher. Pacher made the altarpiece between 1471 and 1475. During the Baroque era, the altarpiece was considered out of date and replaced with a Baroque high altar. Pacher's altarpiece was placed in the St. Erasmus' chapel of the church. It has remained there since; it has however lost its wings, its predella, its top and other details.
References:Sigmaringen Castle was first mentioned in the year 1077 in the chronicles of Petershausen monastery. The oldest parts of the castle are concealed beneath the alterations made during the 17th and the 19th centuries. The secret of the earliest settlement built on this defendable rock will never be fully revealed: large-scale excavation work would be necessary, which the extensive land development renders impossible. Judging from the many Roman remains unearthed in the area around Sigmaringen, the 12th century keep known as the 'Roman Tower' could be traced back to a Roman predecessor.
The castle remains that have been preserved (gate, great hall and keep) date back to the Staufer period around 1200. The castle remains were integrated into subsequent buildings. The foundations of the castle buildings are to a large extent identical to the surrounding castle wall.
These remains give us a good idea of how the castle might have looked during the 12th century.
