Ornate stone superstructure to the ancient town well, built in 1868 by the Corporation of Nefyn, Robert Thomas and John Jones, bailiffs, according to the inscription, which also records Lord Newborough as mayor and presumably promoter of this unusual building.

Sides have blank recessed arch each side with raised rusticated surrounds and raised angle quoins. Plain projecting course above under pyramid roof, which has tooled stone blocks for the angle ridges and a square apex piece under finial. Each face has a stone steep gablet with slate plaque inscribed:
