TAL-Y-CAVN, a hamlet (detached), in the parish of LLANBEDR, union of Conway, hundred of LLECHWEDD-ISAV, county
of CARNARVON, NORTH WALES, 7 miles. (S.) from Llanrwst. This isolated spot, though forming part of the parish of Llanbedr,
is entirely surrounded by that of Caerhen, and is situated upon the western bank of the navigable river Conway, across
which is a public ferry to Eglwys-Bach, in the county of Denbigh. This is the only ferry between the bridges of Aberconway
and Llanrwst, and near the approach to it is a small artificial mount, on which was once a tower or castle, erected to
defend the pass, but of which there are not now the slightest vestiges; it is said by Camden to have been called Bryn-
Castell, and to have served as an exploratory tower forming an outpost of the Roman station Conovium.
