Abstract:		 The work comprised the monitoring of the excavation of two test pits to the east of the Middle Drawbridge, a foundation trench under the Middle Drawbridge and a series of duct trenches across the gate within the Outer Wall at the north of the Middle Drawbridge. It follows from a previous investigation by PCA in advance of the project in 2012. Six archaeological phases were identified. The first, dating to the early post-medieval period, relates to a cobbled surface and associated bedding layer which may relate to the early post-medieval development of the Tower between the Outer and Inner Walls around the Wakefield and Lanthorn Towers. Phase 2 was represented by demolition and make-up layers which could be the result of clearance of the post-medieval development and landscaping of this area in the 19th century. Phase 3, early 19th century in date, was associated with natural sedimentation and the dumping of material into the moat, prior of the construction of the first bridge in 1834. That phase of construction, Phase 4, was evidenced by a brick footing for the first bridge. Phase 5 may be attributable to the draining of the moat in 1843 and its subsequent landscaping, whilst Phase 6 relates to later usage of the area further to its continued resurfacing and landscaping in the 19th and 20th Centuries. Natural deposits were not encountered in any intervention.
