Further test excavation was carried out at this site from May through to December 2004. The site contains the medieval double mills of St Thomas's Abbey, which were powered by the Poddle River. It was the site of the Warrenmount mills, which had a large millpond and complex on the site until demolition in the 20th century.
Excavation focused on the large industrial mill building. The floor level and degree of preservation of the industrial remains was established; this had been extensively disturbed by a recent pipe trench. Several building levels were recognised. Truncated levels of possible medieval or early post-medieval date were present in a localised area. A large oak beam which was reused in the 19th-century Poddle culvert wall was dated by dendrochronology to the late 12th or early 13th century. It is likely that some of the timber structure of the mill remains beneath the floor level of the culvert.
Further work in this area will be necessitated on receipt of planning permission to develop the site.
