Abbey Tower

Freestanding single-bay three-stage bell tower, built c.1460, altered c.1740, now a roofless ruin. Coursed random rubble limestone walls offset at each stage with sandstone string course terminating first stage and carved stone cornice terminating second stage, all with recent cement pointing. Plaque to Owen Roe O'Neill, erected c.1990, to south side of the tower. Round-headed openings to ground floor entrance and four sides of third stage, all with moulded architraves, plinth, impost blocks and keystones.

The Franciscan order was brought to Cavan in 1300 by the O'Neills and remained until the sixteenth century. The bell tower is the only standing remnant of the medieval Franciscan church, and is therefore of archaeological and historical interest. The use of the tower as part of parish church until the early nineteenth century may be seen in the carved door and window surrounds, which add to the architectural interest of the structure. The tower contributes to the historical architectural landscape of the town and its survival reflects layers of the town's development and history. The association with Owen Roe O’Neill (c.1590–1649), the celebrated general in the Irish Confederate War, adds to the site's historical interest.
