Cickini is an early Christian church constructed in the 6th century AD, maybe at a location of a Roman village that dates to the 1st century. The bishop of Krk used the location as a temporary refuge. It is believed to have been abandoned after the 9th century. In addition to the church there is a 2,500 sq meter residential complex that has yet to be excavated.
The remains of church was discovered in 2002. A small museum dedicated to the site is located in Sveti Vid. The museum contains artifacts that have been excavated from the site, including tablets.
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.
