The Santa Maria del Sepolcro is a gothic-style church in Potenza. The church is located at the crossing of two Roman roads, and is the locale where tradition holds that the St Gerard of Potenza, then bishop of the town, transmuted water into wine.
A church was erected in the early 12th century by the Knights Templar, but was placed under the bishop in 1314. Rebuilt in 1488, and refurbished in 1652, at which time, the church was affiliated with an order of observant Franciscans.
The interior has a baroque altar (1656) with an urn putatively holding a relic of the blood of Christ. The nave ceiling has octagonal gilded wood cassettoni. The church has a 16th-century Immaculate Conception with St Francis and St Roch; a Madonna of the Graces with Saints Francis and Patrick (1582); and a Adoration of the Shepherds by Giovanni Ricca.
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.
