By the second half of the nineteenth-century the burial chamber had been partially dismantled, with the capstone lying nearby. Later, the southern support also fell and the eastern support began to lean. The monument's present condition is the result of a 1936 reconstruction. Notice was made in the eighteenth and nineteenth centuries of a possible avenue of stones which may have formed an approach to the burial chamber, but the RCAHMW's Inventory of the Ancient Monuments in Caernarvonshire (1964) notes that 'there is no sign of these structures at the present day, unless the former reference [Farrington (1772)] is to the two standing stones, Nos. 1514 (i) and (ii) [Nprn 302353 and 308128].'
