The Gothic castle of Telč was built in the second half of the 14th century by the lords of Hradec. At the end of the 15th century the castle fortifications were strengthened and a new gate-tower built. In the middle of the 16th century the medieval castle no longer satisfied Renaissance nobleman Zachariáš of Hradec, who had the castle altered in the Renaissance style. The ground floor was vaulted anew, the façade decorated with sgraffito, and the state apartments and living quarters received stucco ornamentation together with trompe l'oeil and chiaroscuro paintings in 1553. The counter-reformation brought the Jesuits to the town, who built the church of Name of Jesus in 1666-1667, according to the plans of Domenico Orsi. The column of the Virgin and the fountain in the centre of the square date from the 18th century.
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.
