Description
Parliament House is a Grade II listed building that was originally a terrace of four cottages but has since been converted into two dwellings. The gable wall facing High Street features fragmentary remains of medieval masonry, including an inscribed stone that states: 'This fragment is the remains of the building where Edward I held his parliament A.D. 1283, in which was passed the Statute of Rhuddlan, securing to the Principality of Wales its judicial rights and independence'. There is a 13th-century doorway and a 14th-century cusped ogee window, both of which are blocked and likely originated from the nearby castle. However, there is no evidence linking this building to the site of the parliament of 1283. The main elevation facing Parliament Street has undergone significant modifications, but each house retains a doorway on the left and features three renewed windows on the ground floor, with two additional windows above, all having cambered brick heads.
