During October/November 1992, a cable trench was dug westwards from the front of Maison Dieu House, to the north-eastern pavement of Biggnin Street. Three ancient walls were exposed under the Biggin Street pavement. From the mortar used in two of these walls, it seems fairly certain, they are of Medieval date (one also contained fragments of slate and peg tile). (1)

It seems probable that these walls were contemporary with each other and that they joined at an approximate right angle to form the south-west corner of a structure. From the depth of one (0.40m) it does not seem to have been a cellered structure and it seems most probable that the walls belonged to the outer boundary wall of the Medieval hospital complex. (2)
