In 1870-72, John Marius Wilson's Imperial Gazetteer of England and Wales described Caerhun like this:
CAERHUN, or Caer-Rhun. a village and a parish in Conway district, Carnarvon. The village stands on the Conway river, near the Conway and Llanrwst railway, 5 miles S of Conway. It occupies the site of the Roman Conovium; has yielded many Roman relics; and is a pretty place. The parish includes also the townships of Isar-afon, Maen-y-Bardd, Penfio, and Rhwng-y-Ddwyafon; and its Post Town is Llanrwst. Acres, 13,402. Real property, £4,687. Pop., 1,314. Houses, 313. The property is divided among a few. The surface comprises mountains, glens, and chasms; and is highly picturesque. The living is a vicarage, annexed to the rectory of Llanbedr, in the diocese of Bangor. The church is good; and there are dissenting chapels.
