Various items were found in the excavation: a fine 13th century painted glass head, fragments of a Near Eastern medieval glass vessel, tiles and pottery and bits of bone and metal including a key. Also a Malvern series wall tile dated 1457/8, a very poor tile (a 'waster'): it is probable that this had been made at the Dale kiln (see later) from a stamp supplied from Great Malvern. Worked stones and roofing materials were also found.  

At the end of the slype, Professor Colvin found foundations of a wall running north and south, and further substantial foundations including a buttress to the east of this. These foundations were visible in the Abbey field in Victorian times.  

Five other infirmaries connected with Premonstratensian abbeys are known:  Alnwick, Easby, W. Langdon, St Radegund’s, Shap; possibly also Langley and Croxton. The normal position is east or south-east of the claustral block; they have a hall of some size, but no evidence of a chapel, and bear no resemblance to the aisled plan of the older orders. Easby’s is on the other side of the cloister and Alnwick’s is just a mess of foundations.

In the field to the south of the abbey field with its hidden infirmary foundations are fishponds: mention was made of these in 1490.  Foundations of walls damming the brook to form these fishponds can also be found.

Turning right out of Abbey House’s drive and walking along the road, turning right at the triangle, we find the former Methodist Chapel now known as the Gateway Christian Centre. Just beyond this building to the north is a gravelled drive which is a public footpath. On the left of this drive are the remains of St Mary’s Abbey’s gatehouse. It is about 150 yards north west of the Abbey site.  The square head and chamfered jambs of the windows suggest that it dates from the 15th or 16th century. There is a pier and spring of an archway to the gateway on the north wall of the gatehouse; the angle buttresses are gone. In Buck's sketch of 1730 two arches can be seen spanning the roadway.

In more recent times the building was used as a gaol, sheltering prisoners being moved from Nottingham to Derby. The upper storey of the building was used as a Methodist Chapel from when the time when the original chapel burnt down until 1902, when the present chapel was built. At one stage the lower vaulted chamber of the gatehouse was used as a coal house for the Chapel. Later the gatehouse was used as a bakehouse, and contained an oven and copper. Until the winter­ of 1935/6 when the oven collapsed, the meat for the Whitsun Feast of the Dale Abbey Society for the Prosecution of Felons was cooked there - plumpudding was baked in the copper.
