Northern aisle of the Cistercian Abbey of Corcomroe, County Galway, Ireland. The church, which dates from 1210 to 1225, was planned as a reduced version of the normal Cistercian scheme with only one chapel opening off each transept (so a narrower aisle was required) and the aisle and its arches are not arranged symmetrically north and south and there is some doubt about whether a north aisle was ever built.
