Cong abbey was a fascinating spot. It is probably built prior to the medieval times. Inside the abbey (which is in ruins now), you would see graves that are old, and some that are relatively new (from 90s and 80s). Inside the abbey there were slippery stairways that were so dangerous to get on, and some small gardens that are kept neat all the time. This window specifically is for a chamber that lost its roof, and as far as I remember, there were two graves embedded into the ground in this chamber, but I didn't have the chance to read for whom!
