It is a cross-base, almost perfectly square at roughly three quarters of a metre on each side, with a mortise, the socket cut into the top to receive an upright cross, positioned very slightly off-centre. When it was recorded in November 1983, it was lying flat on the ground about four metres to the south-west of the associated well. Nobody knows when it was made.

The well it belongs to is Our Lady's Well, a site with the kind of long, layered significance common to holy wells in the west of Ireland. Holy wells were focal points for popular devotion long before and long after the formal structures of the church took root, and many remained active pilgrimage sites into the modern era. This one was subject to considerable attention from the late 1980s onwards. FÁS schemes, the state-funded community employment programmes of that period, carried out works on the well and its surroundings between 1987 and 1989. Then, in the 1990s, the area was developed further as a park to mark the millennium year of 2000. The cross-base, lying on the ground and unattached to anything, was almost certainly moved during one or more of these phases of work. Where exactly it sat before, and whether it ever stood upright in its original location, is not recorded.
