NHER 50583 (Monument record) - Post medieval extractive pits, open ground and Victorian terraced houses, Botolph Street/Anglia Square

March 2007. Desk-based Assessment.
The site is located within the Late Saxon town and the medieval city walls, and therefore the potential for archaeological finds and features is significant. The northern gate of the Late Saxon town may have been located within the development area. During the medieval period the nature of the area was predominantly industrial, including iron-working.

September-November 2007. Trial Trench and Borehole Survey.
Evaluation of area to be affected by proposed redevelopment of Anglia Square (Area 3; Trench 12 and Window Samples 1-9).
Trench 12: The earliest activity recorded in this area is the extraction of two quarry pits, which were probably dug in the post-medieval period. This trench was located within the area known as St Margaret's Croft and cartographic evidence indicates that this area remained open ground until the second half of the 19th century. A layer of former garden soil probably relates to horticultural activity during the last 150 years of St Margaret's Croft. This was overlain by a series of walls of soft red brick with associated brick and Portland cement floors. These cannot have been associated with the small cottages depicted on the 1885 Ordnance Survey map of the area, but more likely relate to the terraced houses that are visible on maps of the same area from 1905. These buildings were demolished in the 1940s or 1950s.
