To quote from a leaflet available at SN2138 : Capel Colman: "this is a most remarkable ornamental grotto, and a rare survival in West Wales. It was built in the late 1820s for Morgan Jones the Younger (1787-1840), who inherited the Cilwendeg estate upon the death of his uncle. It is believed the ladies of Cilwendeg Mansion devised the original patterns for the interior decoration. This consists of a profusion of native seashells, minerals and coloured glass fragments arranged in primitive patterns and impressed into lime mortar panels."
