Plas mawr, (the great mansion) an old house in the centre of the town, built by Robert Wynne, Esq. a branch of the Gwydir family, in the year 1585, will be likely to attract the traveller’s attention. Over the gateway are the words Anechou, Apechou, sustine, abstine; and on the House these capital letters, IHS. X.P.S. being the Ancient method of inscribing our Saviour’s name. The Church, the ruins of an old Abbey, and another old House, called the College, also claim a visit from the stranger. Gyffin, a Parish Church, about half a mile off, on the road to Llanrwst, is a Stipendiary Cure, and is generally annexed to Conway. The late Doctor Jones, Dean of Bangor, left £100. the interest of which he directed to be applied to the keeping of a School here. The Vicarage of Conway, as well as Gyffin, are in the patronage of the Bishop of Bangor. On the summit of the hill below the town, and nearly opposite to the bifurcated rock, on which stood the Castle of Diganwy, are the ruins of an ancient fortification, of a circular form, with only one entrance, and this probably is the place mentioned by Leland, in his Itinerary, and which he denominates Sinnodun, and where, he says, there are the remains of a great work; it is described by him as being a mile out of the town, but in what direction is not mentioned. Camden also mentions a British Post, called Caer Lleion, surrounded by Ditches and strong Ramparts, on a lofty hill, near Conway marsh. The Castle of Sinnodun is also represented as being situated near this place, in a Map of the County, annexed to a very old edition of that Author’s Britannia. As this small work is intended merely as a guide to the Tourist, in his excursion through the County, it cannot be expected to contain a very _detailed_ or _particular_ account of every object, which may deserve attention; for this reason the Compiler must pass over the siege of this Castle, during the Rebellion, in Oliver Cromwell’s time, and merely observe, that the custody of it was committed by the King to Archbishop Williams, of the Penrhyn family, near Bangor, and after the gentlemen and freeholders of the neighbourhood had placed a number of valuable articles under his care, and for which he had given them receipts, and thus became answerable for the property, he was, in 1645, cruelly dispossessed by Prince Rupert, without assigning any reason for this strange conduct; it was taken, however, from the Prince in June, 1646, by General Mytton. The Archbishop was buried in the Church of Llandegai, near Bangor, where his Monument is still to be seen.
