The Bwlch y Ddeufaen Standing Stones straddle the Roman Road from Rowen to Llanfairfechan. This road was the main route between the Roman forts of Kanovium (in the Conwy valley) and Segontium (near Caernarfon). However the many standing stones and cairns along this stretch indicate that this was an ancient prehistoric trackway used for thousands of years before the Romans came to Wales.

The south east stone is 3 metres high and the north west stone is 2 metres high. Various other smaller stones which might have formed part of a 'stone setting' can be seen near the north west stone.
