The ruins of the Earl's Palace lie near St Magnus's Cathedral. Built by Patrick, Earl of Orkney, construction began in 1607 and was largely undertaken via forced labour. Earl Patrick is widely acknowledged to have been one of the most tyrannical noblemen in Scotland's history.
The palace was built after the Earl decided that the accommodation provided by the Bishop's Palace was inadequate for his needs. He decided to extend the complex by building a new palace on the adjoining land. This was complicated by the fact he did not actually own this property. He quickly acquired it by fabricating charges of theft against the unfortunate owner, trying him and having him executed. Upon his imprisonment at Edinburgh in 1609, his bastard son Robert began a rebellion on his behalf and seized the palace, along with nearby St Magnus's Cathedral and Kirkwall Castle. An army led by the Earl of Caithness laid siege, and the Castle was destroyed. Earl Patrick and his son were later executed for treason.
After the Earl's death the palace continued to be the residence of the Bishops of Orkney sporadically until 1688, when it became the property of the Crown, and fell into ruin in the 18th century. It is currently in the possession of Historic Scotland. The ruins, though roofless, still have much of their original French-influenced Renaissance elegance. Turrets and decorations carved in the sandy coloured stonework, give glimpses of the former splendour of this residence.
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.
