The gate house at Cors-y-Gedol was built by William Vaughan in 1630 and is thought to have been designed by Inigo Jones, though this is doubtful. Nevertheless the gatehouse is exceptional, being renaissance in spirit and no later than Jacobean in form. The 3-storey building is of stone, with a cross gabled slated roof; stone mullioned windows; a stone segmental arch and 2 storey wings. The arch is moulded, and the keystone bears the date and the initials of William Vaughan. In the upper storey is a single handed clock face with pointed hoodmould over; at each corner of the tower's roof is a crude gargoyle in the shape of a human face. There is a timber bellcote with pyramid slate roof surmounted by a weathercock. The gatehouse was converted for use as holiday accommodation in the late 20th century.
