It must have been impregnable against any attack when fortified in the days of rude warfare. Its early history is somewhat obscure. It was in 1200 the residence of Madoc ap Griffith, the founder of Valle Crucis, from which it is distant only two or three miles. Madoc, it appears, became a traitor to his king, and when he afterwards gave in his submission it was readily accepted, for the probable reason that the Sovereign was aware of the impregnability of his castle, to which he had retired. Llangollen Church has recently been “restored.”--The excursion on Friday was in the direction of Corwen. Commencing at Llangar Church, a short drive from Bala, an inscribed stone in the town was noticed. It bore the inscription Cavoseniagii, but its interpretation is a matter of controversy. Next came Tomen-y-Castell, another of those mounds common in the district; in this case it appears to have been placed as a means of defence and observation on an important part of the Roman road leading from Caergai towards Deva (Chester). Caer Creini was next visited--a fine stone-breasted outwork. At Rhug Chapel attention was called to some good carving in the roof. Caer Drewyn is a large fort with stone ramparts. Corwen Church was then reached. This is another restored church, but here a fine effigy of a former priest is untouched. Llangan Church, also restored, has a good screen and a portion of a pastoral staff, ascribed to the founder, Dorfel Gadarn. Caerbont was next visited. This is mentioned by Mr. Hartshorne as belonging to the type of forts of the dry stone-walling period. In the evening the concluding meeting was held at the County-hall, Bala, when the Rev. Canon Thomas read a paper on the “Ecclesiastical History of Merionethshire.”--A small local museum of antiquities was formed during the week at the Calvinistic Methodists’ College, Bala. It contained some numismatic specimens and a few rare books, among them poems of Phillipe and Catherine ap Howell. A curious almsbox was shown, so contrived that an arrangement of teeth prevents the abstraction of coins placed therein. Some painted iron crosses, said to be from Cymmer Abbey, were also shown, the date said to be Henry VIII., but bearing the appearance of more modern origin.
