The Church of the Addolorata is a Romanesque-style basilica church in Acqui Terme. The church is dedicated to the Marian devotion of Our Lady of Sorrows, however, the church is also called San Pietro, since it was once attached to what was once the adjacent Benedictine monastery of San Pietro.
The layout we see today was built in the 11th-century at the site of a late 6th-century paleochristian church located just outside the city walls. It had three naves with an octagonal bell-tower at the southern apse. The simple brick facade has protruding pilasters and shows a trend towards verticality. After 1720, with the closing of the monastery, part of the church was rededicated to the Addolorata. It underwent major restoration after the First World War, that stripped much of the decoration, giving the interior a white-washed simplicity. The apse and the base of the bell-tower retain medieval traces.
The interior conserves a 15th-century Deposition fresco and two 16th-century canvases depicting Christ Crowned with Spines and Christ before Pilate. The wooden statue of the Madonna Addolorata dates to 1720.
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.
