Pentrefoelas

• Plas Iolyn, home to Rhys Fawr ap Maredudd, his son Robert ap Rhys, his grandson the 16th-century MP Elis Prys and his great-grandson, the poet Tomos Prys. It is now a farmhouse.
• Gilar, built in the 16th century for the poet Rhys Wyn ap Cadwaladr, perhaps by his father Cadwaladr ap Maurice after receiving a substantial grant of land from Henry VIII in 1545–1546, which included the land later occupied by Plas Iolyn and Old Voelas House.
• The village had a chapelry of Ysbyty Ifan built in 1766 and known as Voelas Chapel. The Parish Church was built on the same site in 1857–1859.
• The Pentrefoelas watermill for grinding flour dates from 1815 and was restored by Clwyd County Council as part of a heritage scheme. The ironwork for the external overshot waterwheel was originally cast by the Llanrwst Foundry probably sometime in the 19th century
