Roman barrow cemetery with possible Bronze Age origins. Only one survives as an earthwork, this was enlarged for use as a Medieval motte and bailey and a windmill mound. It was also used as a Civil War gun emplacement and incorporated into a public garden after 1790. (PastScape)
Excavations took place in 1981 prior to redevelopment on the site of the old City Council offices at 15A Dane John. The site was situated immediately adjacent to the west side of Dane Gardens, about 100 metres north of the Dane John mound. Extensive later disturbance had removed all but a few Roman deposits. The next major archaeological phase consisted of part of a large ditch, 17 metres wide, 3 metres deep and was probably part of the outer bailey ditch for the early Norman motte and bailey castle - the present Dane John mound probably being the site of the motte. In the late 12th or 13th century, the bailey defences were probably razed and the ditch partially backfilled. A number of features, including pits, wells and small ditches, were then dug in the area. The features were later truncated and disturbed. The partly backfilled bailey ditch was re-cut at this time with a channel at the sump. This new ditch, which may have been an open running sewer, might be the predecessor of the 'Black Ditch' or 'Black Dyke' which documentary sources describe as being an open sewer extant in this vicinity until the eighteenth century. The re-cut bailey ditch was progressively backfilled and virtually levelled by the sixteenth century. The area then became a garden throughout the 17th century and towards the end of this period part of the slope of the area was terraced and a trackway constructed. In the 18th century levelling up and terracing occurred. In 1790 the 'Dane John land' of which the area covered by the site was part, was leased by the City Alderman, James Simmons, who undertook to level the site and landscape the entire gardens
This landscaping was still in progress in the early 19th century. From around this time a large amount of dumping occurred on site, raising the level by about one metre. These deposits were cut by the foundations of Shakespeare's Terrace (Nos 12-15 Dane John) constructed at some time in the 1840's and by a boundary wall and brick-lined well. Sealing all of these features was a thick layer of 20th century dump deposits, over which lay the shallow foundations of the recent City Council offices. (PastScape ref. Frere et al, 1987)
