Nantyffin Cider Mill. The main building is still there but some outbuildings to the S have been lost to road alterations. The short lane to the yard preserves the old line of the A479. The 1953 map shows the correct height but the actual position of the BM is unclear, although seemingly not on the extant buildings.
