Cadw's description

Situated opposite Ty Mawr and at right-angles with it.

Late C17 rubble barn with old slate roof, set into the slight slope of a hill. Central entrance to W side with flanking ventilation slits; 3 entrances to the E side, advancing up the incline, that to the L with a boarded door; further ventilation slits. Attached to the E wall between the lower entrances an iron shaft connected to a surprisingly large C19 iron mill wheel; this sits in a rubble-walled water channel immediately to the E of the barn; wooden spokes. This possibly powered a feed mill.

Included for group value with Ty Mawr.
