The Electoral Palace was the residence of the last Archbishop and Elector of Trier, Clemens Wenceslaus of Saxony, who commissioned the building in the late 18th century. It was erected between 1777–1793. In the mid-19th century, the Prussian Crown Prince (later Emperor Wilhelm I) had his official residence there during his years as military governor of the Rhine Province and the Province of Westphalia. It now houses various offices of the federal government.
The Electoral Palace is one of the most important examples of the early French neoclassical great house in Southwestern Germany, and with Schloss Wilhelmshöhe in Kassel, the Prince Bishop's Palace in Münster and Ludwigsburg Palace, one of the last palaces built in Germany before the French Revolution. Since 2002 it has been part of the Rhine Gorge UNESCO World Heritage Site, and it is also a protected cultural property under the Hague Convention.
References:The Broch of Gurness is an Iron Age broch village. Settlement here began sometime between 500 and 200 BC. At the centre of the settlement is a stone tower or broch, which once probably reached a height of around 10 metres. Its interior is divided into sections by upright slabs. The tower features two skins of drystone walls, with stone-floored galleries in between. These are accessed by steps. Stone ledges suggest that there was once an upper storey with a timber floor. The roof would have been thatched, surrounded by a wall walk linked by stairs to the ground floor. The broch features two hearths and a subterranean stone cistern with steps leading down into it. It is thought to have some religious significance, relating to an Iron Age cult of the underground.
The remains of the central tower are up to 3.6 metres high, and the stone walls are up to 4.1 metres thick.
