Description
Parliament House began as a terrace of four cottages and is now divided into two dwellings. The building incorporates fragments of medieval masonry in the gable wall facing High Street, including an inscribed stone that claims the site was where Edward I held parliament in 1283, and where the Statute of Rhuddlan was passed, safeguarding judicial rights and independence for the Principality of Wales. A 13th-century doorway and a 14th-century cusped ogee window, both blocked, are incorporated within the masonry but are likely from the castle and not in their original location. It is important to note that there is currently no evidence to connect a building on this site with the parliamentary events of 1283. The main elevation, facing Parliament Street, has undergone significant alteration. Each dwelling has a doorway on the left side, with three renewed windows on the ground floor and two windows above, all with cambered brick heads.
