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: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.
