Plas Newydd is a country house set in gardens, parkland and surrounding woodland on the north bank of the Menai Strait, near Llanfairpwllgwyngyll, Anglesey, Wales. The current building has its origins in 1470, and evolved over the centuries to become one of Anglesey's principal residences. Owned successively by Griffiths, Baylys and Pagets, it became the country seat of the Marquesses of Anglesey, and the core of a large agricultural estate. The house and grounds, with views over the strait and Snowdonia, are open to the public, having been owned by the National Trust since 1976.
Plas Newydd was remodelled by John Cooper of Beaumaris in 1783-6 and between the 1790s and 1820s by James Wyatt and his assistant, Joseph Potter of Lichfield. Their client was Henry, Earl of Uxbridge; his son Henry, who lost a leg at Waterloo, was created 1st Marquess of Anglesey. Architecturally, Plas Newydd belongs to the early 19th century and the ‘cult of styles’, cheerfully mixing Neo-classical and picturesque Gothick. Still, it is very much rooted in the 1930s, when the 6th Marquess of Anglesey refurbished the house and employed Rex Whistler to create an immense Italianate dining room mural. Aside from the mural, the interior is mainly Neo-classical with very good examples of late 18th-century Gothick work in the hall and music room. Outside, the sinuous shape of the landscape, framed by drifts of trees and shrubs, was set out by the leading designer of the period, Humphry Repton.
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.
