Built as a single-room church school in the early C19. It closed in 1866 and the children were transferred to a new school in the nearby village of Groes. Used as a museum for early Christian stones since 1932. Conserved and interior remodelled 1998-9 by Cadw.


Two-storey 3-window range of rubble stone with quoins, under a red tile roof with stone stack to W end. Lean-to porch at W end containing late C20 glazed panels and door. The S face has round-headed windows under voussoir heads with stone sills. Iron multi-pane windows with radial glazing under arches. The E end has a 3-light metal-framed window with quarries under a square hoodmould and with a stone sill. Two similar windows to N side and 2 large rooflights.


Inside the porch are 2 doors. That to the R is original with a large stone lintel. The single-room interior has been converted to a museum and has a steel-framed gallery.
