Maen Huail is a stone block at St Peter's Square, in the centre of Ruthin, Denbighshire, North Wales. A circular plaque next to it states "Maen Huail on which tradition states, King Arthur beheaded Huail, brother of Gildas the historian". The stone was recorded in 1699 as being in the middle of the road, and now stands on a concrete plinth against the half-timbered wall of the Barclays Bank building, a 20th-century copy of the now mainly destroyed Exmewe Hall.The legend probably originated as an oral tradition, and is first recorded in the Chronicle of Six Ages of the World by Elis Gruffydd, dating to around 1550. The stone itself is thought more likely to be a market or civic stone, or a preaching stone. It is a craggy and heavily weathered limestone boulder, measuring 1.2 metres (3.9 ft) long, and some 0.6 metres (2.0 ft) high and wide.

The Morning Star (or The Star Inn), Ruthin was listed as a Grade II building on 16 May 1978. It is directly opposite the Ruthin Gaol, and is claimed to be the oldest pub in Ruthin.Early in 2010 a cache of old documents was discovered in the roof of the Morning Star. They were four very dirty, tightly screwed up bundles of papers giving detail on the business of an alehouse and on ordinary life in early Victorian Ruthin. They are about John Williams who was the last of five family members to hold the licence for the Star in the early nineteenth century. The Star was originally built in 1639, as a lobby-entrance building with integral rear wing. The inn was known as the "North Pole" in 1756 with James Edwards bricklayer as the licensee; it became the "Star" in 1775 with Richard Percival, also a bricklayer, as the licensee. Finally it was renamed the Morning Star in 2010. An 1845 description mentions that the public areas were at the front of the building, with a bar and a parlour either side of the lobby entrance. Behind these was a kitchen and a brewhouse and pantry to the rear. A cellar lay below the public areas. Upstairs, there were four bedrooms, above which were lofts intended for the Star's servants.
