From the Wikipedia article
Great Castle House is a former town house built on the site of part of Monmouth Castle in Wales. Amongst the town's most significant buildings, it has a Grade I listing and is one of 24 sites on the Monmouth Heritage Trail. The house is located on Castle Hill, off Agincourt Square in Monmouth town centre. Described as "a house of splendid swagger outside and in", it was completed in 1673 for Henry Somerset, the 3rd Marquis of Worcester, who was Lord President of the Council of Wales and the Marches. It later became an Assize Court, until the Court moved to the new Shire Hall in 1725. It has been the Headquarters of Royal Monmouthshire Royal Engineers (Militia) since the mid-19th century, and contains the Regimental Museum.

Background
History
When Worcester was appointed to the post of President of the Council of Wales and the Marches, he decided that he needed a seat in the Marches appropriate to his status. The house was primarily intended to be used for ceremonial and official, rather than domestic, purposes. The interior is described as "astonishing", particularly for its plasterwork. When the Assizes moved to Shire Hall in 1725, the house became lodgings for the judges (though part of it was let to a maker of drainage pipes), but later they moved to less spacious lodgings in the town, and from about 1760 the house provided a high-class school for young ladies.
