Excavation in 2003 and 2004 at a site adjacent to Beeleigh Abbey near Maldon, Essex has revealed the well preserved foundations of a medieval hall building. All the evidence from a large number of artefacts points to a late 15th/early 16th century date and a building associated with the abbey. Six hearths have been uncovered in situ, three of which have been subjected to archaeomagnetic dating by English Heritage. Two have confirmed the late 15th/early 16th date. The third, relating to a previous hall, yielded a mid 13th century date. The site at Tollesbury was revisited in the Autumn of 2003 and several trial trenches were dug, one of which yielded a quantity of Transitional Iron Age pottery. Further work will be done in 2004.
