Gars am Kamp Castle was built around 1120-1130. The heterogeneously arranged complex of the hilltop castle stands on terraced land descending in three levels by the Kamp River.
On the highest level stands the main castle, enclosed by a ring wall. On the second, middle plateau, there are the southern gate tower and the castle chapel, a hall building from the 16th century to the west, and the surrounding fortifications from the 13th century. On the third, lowest level, connected by a castle path, the fortified outer bailey hosts the parish church of Thunau am Kamp on a southern terrace. A small coat of arms stone of the Rotthal family (dated 1709) is located above the portal to the north tower.
Duino Castle was built by the Wallsee family in 1389 on the cliffs overlooking the Gulf of Trieste. It replaced an older castle from the 11th century. Over time, the Wallsee family disappeared and the castle, after having been used as a prison, became the residence of the Luogar and Hofer.
At the end of the 19th century it became the property of Prince Alexander von Thurn und Taxis from the Czech branch of the House of Thurn and Taxis. It remains with the family to this day with his great-grandson Prince Carlo Alessandro della Torre e Tasso, Duke of Castel Duino the current owner. The castle has been opened to the public as a museum and park.
