Early Christian site with round tower with plain round-headed doorway and ruined church of later date. One piece of Romanesque carved stone is preserved at the site.

The foundation of the monastery is attributed to St Benen or Benignus, a 5thc. saint. The annals record the burning of the settlement in 1114.

This voussoir is the only remaining trace of a Romanesque building that must once have occupied the site. Rosettes within lozenges are also found at Annaghdown (Galway), Killaloe Cathedral and Tomgraney (Clare).
