Description

Cwt Gwyddau is a single-storey cottage located at the southwest corner of Tyddyn y Felin. It is constructed from random rubble masonry, featuring large stones as quoins and lintels. The roof is made of slate with stone coping and a tiled ridge. The building has low doorways that are widely spaced at each end of the north lateral wall, suggesting it was likely used as a storehouse. The interior of the building was not inspected during the survey.
