The Trinity area, which was built in the latter half of the 17th century and first half of the 18th century, is a fine (and rare) example of early industrial housing. Over 300 houses were built between 1660 and 1756 in a very unusual early example of a planned grid-pattern. Although about half the area was demolished in the 1960s under a Slum Clearance Order, before its historical importance was realised, the remainder was saved and was restored at a cost of £4 million between 1980 and 1984.
