a Grade II* listed building. Porth y Dŵr At No. 65 Clwyd Street, this Grade II* listed building retains much of the medieval timber frame internally, the oak for which was felled in 1455 and 1456. Its original purpose is unknown, although it has a medieval arched doorway facing towards the 13th-century mill, and a 15th-century solar (private living quarters) with an open roof with cusped windbraces.

The house retains a name referring to its connection with Irish drovers attending markets and fairs. Other establishments of interest include No. 1, now Boots, formerly the Raven Inn, which in 1560 may have been the birthplace of Bishop Richard Parry, pupil and master (1584) of Ruthin School. He was involved with Dean Gabriel Goodman and others in translating the Bible and prayer book into Welsh. The main contributor was Bishop William Morgan, but Parry's revision in 1620 became the accepted authorised version. The Ruthin Royal Bowling Green used the Raven as their headquarters until the Cornwallis-Wests came to live in Ruthin Castle. The club met at the Raven for its annual and quarterly meetings. When competitions took place, the staff of the Raven would take "cwrw da" (good beer) to the players. With the arrival of the Wests, the bowling green laid out inside the curtilage of the castle forced the club to find an alternative green. The option accepted was the rear of
