The Royal Collegiate Church of Roncesvalles was built in the French Gothic style. King Sancho VII built this church in the 13th century as part of the hospital’s facilities in Roncesvalles; its purpose was to provide succour to pilgrims on the Way of Saint James after crossing the Pyrenees. Highlights include the cloister, the chapel of San Agustín, the chapel of Santiago and the crypt, consisting of a straight section of barrel vault and a pentagonal apse. The walls and vaults are covered in mural paintings dating from the 13th century. The art treasures of the Royal collegiate church are housed in a museum in one of the rooms in the church, and include a particularly interesting collection of precious metalwork, exhibited in six display cases. Also outstanding is a chess set belonging to the Emperor Charlemagne, a Renaissance silver chest and a silver-plated wooden statue of the Virgin and Child. There is also a selection of paintings, books and sculptures.
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.
