Porth-y-carn, Porthycarne Street, Usk, Monmouthshire is an early 19th-century Neoclassical villa. Built c. 1834 for Thomas Reece, the agent of the "iron king", Crawshay Bailey, it is a Grade II* listed building.
The architectural historian John Newman suggests a construction date of 1834-5. The client was Thomas Reece, who served as the agent for the industrialist Crawshay Bailey. Reece also served as a Justice of the Peace, in 1845 serving on a committee of justices to enquire into allegations of misconduct against the governor of the Usk House of Correction.[1] Reece died in 1853.[2] In the year before his death, the house had the highest rateable value of any property in Usk. Porth-y-carn remains a private residence.
The villa is of two storeys, the doorcase flanked by a Doric columned porch. Cadw suggests that the interior retains some of its 19th century fittings and furnishings.
