Little Castle (Mali grad) in Kamnik was constructed in the 11th or early 12th century at the strategic site above the narrow passage near an important trail. The Romanesque chapel of St. Eligius is one of the most important Slovene medieval monuments, despite later alterations, and is one of the oldest of its kind in Europe. The chapel features a wooden ceiling and exquisite fresco paintings.
Archaeological evidence indicates a cultic centre here in pre-Antiquity. The castle was first mentioned in 1202, but is of older origin. At the end of the 13th century, the castle burned; the northeast part was demolished and never rebuilt. The remainder of the castle was torn down in the 16th century after the earthquake of 1511, leaving only the three-storey Romanesque chapel built between the 11th and 15th centuries. One can still see the remnants of defensive walls and the recently restored defensive tower.
The first chapel of St. Margaret with a crypt, the presbytery of today's lower chapel, was built around 1100. When the nave was added, the Romanesque portal with a lunette was displaced. In the 13th century the chapel's second floor was built, dedicated to Bartholomew the Apostle, with a Gothic vault build after 1470. The lower chapel was than dedicated to St. Eligius, decorated again after 1771 with frescos by Janez Potočnik. The entire chapel was rebuilt in Baroque style around 1700. Inside there are also remnants of Gothic and Baroque frescos.
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.
