Most of the floor of Kirkstall Abbey is earth, gravel or grass and I was surprised to find these tile fragments in one small cell. The cell (in a row of two or three similar small rooms, though the others had no tiles) had what appeared to be a washing area in the wall, so may have been where the monks washed before meals or prayers. (I may be completely wrong!)
I don't know if the tiles are medieval originals or a later addition - they looked a bit random - but I thought they had a certain charm. So much of Kirkstall's structure has been damaged over the years, though some vaulting and pillars survive.
