The revenues of the monastery at the time of its dissolution, in 1535, were £188 per annum according to Dugdale, but Speed reckons them at £214 3s. 5d. The last abbot was John Hern, who received an annuity of £23 on his surrender. This, together with £10 13s. 4d. to some of the brethren or surviving monks, were the only charges remaining in 1553. It remained in the crown till the 9th of James I., who granted it to Edward Wotton, afterwards created Lord Wotton. In 1654, we find a lady, Margaret Wotton, a recusant, to have been in possession, and that it was put under sequestration by order of the commissioners of the ruling powers. The Abbey now belongs to Rice Thomas, Esq., who is the proprietor of the Trevor Hall Estate, and is under the charge of the Rev. H. T. Owen, by whose kind permission the visitor, on the payment of the small fee of 6d., may inspect the interior. Through the exertions of the Rev. H. T. Owen, some very interesting excavations have been made of late years. During the summer of 1888, Mr. Owen caused some investigations to be made in the Monks’ Dormitory, for by removing surface earth that accumulated there during the time it had been in ruins, five very interesting sepulchral slabs were discovered of very early date, not later than the tenth century. There is one which has a Norman sword on it, and also an inscription which cannot be deciphered but with some degree of uncertainty. It can be read as follows:— “Jacet Oidus Madoc . . . Insignis Cele Ominu Crucis,” which may be translated:— “Here lies Owi dus Madoc, a distinguished Warrior of the Cross of Heaven.” Another stone contains a beautiful floriated cross with a circle, which may be taken for the tombstone of an Abbot or Bishop. There is another floriated circle, in splendid condition, with no inscription whatever. The other two are simply fragments, one having the point of a spear very distinct, and on the other the old Grecian ornament. As these stones form part of the vaulting of the slype, and are of much earlier date than the present Abbey, and were inserted there when the vaulting was erected, it is a certain proof that there must have been a religious house here long before this edifice was erected. Some antiquarians make out one stone to be Anglo-Saxon or Anglo-Hibernia.
