These chisel marks on the brickwork to the doorway have obviously been acquired from some of the fragments onsite and reused in this later repair. The chiseling must have taken off a minute amount of stone so that they sat flush with the wall but we are left with some very beautiful and evocative marks. The original carving, the front of the original stone is now concealed and instead we are now left with the silhouette of the original stone carving against modern mortar.
