The floor reputedly contains original 18" square flagstones or Portland stone. According to rather dubious evidence, there is a crown mark on the underside of the tiles identifying them as having English origin. An architectural problem with the floor is that the present level is too low for the doorways. Either the door openings as well as the doors were larger or the floor was higher. The present structure of a high door step combined with a low floor is most unlikely to be an original construction characteristic.
