On Rain's Eye Plan. In 1783 a walled battery with six guns was built on the Coney Warren near to present day Barrack Street. Much of this was eventually washed away and the rest was demolished by the Sunderland Dock Company in 1848.

On Rain's Eye Plan. The High Street had served as a market area since Bishop Morton's charter of 1634. The wealthier butchers had their shops in the lower part of their houses on the south of the High Street, near The Shambles, and stalls can be seen projecting from houses opposite on the Eye Plan which also shows specialist areas for bakers, seed merchants, vegetables, poultry and dairy produce. The Eye plan also shows stalls of a butchery market in the middle of the High Street between Church and Union street and a market cross (SMR 79). The known Post Medieval market area of the High Street is likely to have had medieval origins.

On Rain's Eye Plan on the Quay side. The 'Commonty' between the High Street and the river in Low Street was used for drying fish. Lawrence Leavebetter owned stone tanks there, used to keep mussels for fish bait. Excavations by Northern Archaeological Associates in 2004 at 172-180 High Street East recorded a stone structure, possibly a stone mussel tank. The land had once been owned by the Chantry of the Virgin Mary at Bishopwearmouth Church, but James I passed it into private ownership. Eventually George Lilburne built a large house on it. Fish was probably thereafter dried on the town moor.

The building of the north pier c. 1785 resulted in a bank of shingle and sand forming at the site of what would become the North Dock in 1837. The area was immediately utilised by the Williamsons for leasing out to ship builders and timber merchants. This is probably the area shown on the Eye Plan as a ship building yard.
