By the following century, the monastery was significant enough for the death of its "superior", Oan, to be mentioned in the Annals of Ulster. The monastery was located within an oval enclosure, surrounded by a ditch, housing a rectangular chapel in the centre, and a handful of smaller buildings either side. A handful of early inscribed stone slabs were located there, of which one bears a Pictish design, comprising a hunting scene; the cross on its obverse is in a style which was fashionable in the 9th century.
