There are pointed-arched doorways on the west and north sides, both adorned with polished dressings and topped by bull's-eye or oculus window openings. An elliptical window opening is located on the south side, while another bull's-eye or oculus window opening can be found on the east side. The structure has been roofless since 1998.
