The first written mention of Íscar was in the year 939 AD in Muslim chronicles. The remaining Christians reconquered Iscar in 1086 AD. Build on the ruins of its ancient fortress, Iscar’s Castle stands majestic looking over the village. The oldest preserved parts of this fortress (probably dating back to the 13th century) are remains of the curtain wall and the inside structure of the tower. To provide a defence against possible attacks from the west side, weak point, the enclosure was re-enforced in the second halfof the fifteenth century for defensive purposes.
At the back of the Main Tower, a large defensive spur, flanked by two turrets transformed the ground floor into the shape of a pentagon.In this side also a new body was added as a defensive barbican, with a small artillery barrier with three circular barrel turrets. And for safety a Moat was dug into the limestone rocks whose access was by a drawbridge.
On one of these turrets appears the shield of Pedro de Zúñiga y Avellaneda and his wife Catalina de Velasco y Mendoza, IICounts of the Miranda del Castañar, which dates this work at between 1478 and 1493.
References: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.
