Plas Newydd

Plas Newydd is a Georgian mansion on the Isle of Anglesey featuring Classical and Gothic architectural elements, with sweeping lawns down to the Menai Strait and an Italianate rose garden. The property combines multiple architectural styles across its grounds, creating varied spaces for visitors to explore.

The estate originated in 1470 when the Griffith family built a hall-house, which was later transformed into the residence of the Marquesses of Anglesey. The building evolved over centuries as successive owners added new features and modified existing structures.

Rex Whistler painted a large trompe-l'œil seascape in the dining room during the 1930s, showcasing artistic skill within the mansion's interior. The work remains visible to visitors today and represents an important example of decorative art from that era.

The National Trust manages the property and uses a marine source heat pump system to reduce energy consumption while preserving the historical structure. This modern system allows the estate to operate sustainably while visitors explore the historic rooms and grounds.

A military museum within the house displays artifacts from the Battle of Waterloo, including items from the 1st Marquess who wore one of Britain's first articulated wooden legs. This personal detail brings together military history with the individual experience of adapting to life after conflict.
