The little isle of Lihou does not possess any Celtic remains, and this has been attributed to its early occupation by the monks, and the erection of a chapel and priory, which were built about the tenth or eleventh century, or some time before the consecration of the Valle church. The site of the chapel presents a heap of walls in ruins, and until lately were shrouded in gloomy night-shade and rank fox-glove, whose tendrils have for years supported the drooping arch, the fallen urn, and mouldering monument; and, as it were in mockery of the dead, clasping the falling column. Remnants of the chapel still remain, and excavations which have heretofore been made, have brought to light many curious details. It consisted of a chancel and a nave, with a square tower on its North-East side. It was vaulted with stone, and the North wall of the nave with a few feet of the roof is still standing. The above excavations were commenced in the chancel, the walls of which were just visible above the turf. It contained the ribs of the roof and portions of the columns and windows, the former of which were of Caen stone. On sinking to a depth of four feet a pavement of small green and red Norman tiles was discovered, and from observations made in different parts of the chapel, it would appear the whole had been thus paved. Under this pavement a few silver monastic coins and pennies of Edward I. were found. A range of buildings may be traced at the lower part of the chapel, overlooking the sea, and others have disappeared from the encroachment of the waves at spring-tides. In a Southern bank is a drain, apparently leading to the kitchen, in which were found large quantities of fish-bones, scales, and other matter. To the East is a walled enclosure, which is said to be the "garden"; at a short distance from this is a round-house or dovecot, where the monks reared their pigeons, and in an adjoining spot is a piece of ground which still goes by the name of the "Cimetière." At one end of the chancel are some steps which appear to be the chief entrance, and the rugged causeway leading from the island to the opposite shore is supposed to have been made by the monks. In the rocks on the South side are two natural baths, supposed to have been hollowed by the attrition of the waters and pebbles, as the action of the waves is remarkably strong here. They are supposed to have been used by the monks during the existence of the priory. The island is very much exposed and scarcely anything besides tufted herbage will grow there; nevertheless there is a good house, containing useful apartments and a fine billiard room and table. Leaving Lihou on the other side of Rocquaine bay is a creek, on which were once some ruins.
