In circa 1682 Sir Ambrose Crowley began an iron manufactory in Sunderland, in a house in Low Street known as the Wear Ice Wearhouse. This was a nail warehouse and manufacturing plant where he could challenge the nail making cartels that operated in the West Midlands. It became his Anchor and Chain Works in 1682. Robinson locates it at the foot of Russell Street and describes it as a stone fronted house. The headstones of some of the windows were of Saxon style, said to have come from St Paul's chapel at the monastery. A carved stone above the door bore the date 1682. Sunderland however was remote from the iron-making district and there were few experienced nail makers in the north-east. Workers had to be brought in. A letter of 1685 indicates that Crowley intended building a slitting mill at Sunderland. Subsequent references to workmen from Liege suggest that this mill was built - it was from Liege that the slitting mill was introduced to England. Crowley did not not stay long in Sunderland before setting up his works in Winlaton village (HER 5987) in 1691 and later at Swalwell (HER 5979). He seems to have abandened his Sunderland enterprise by 1691 following the religious persecution of the largely Catholic specialist workforce that he had brought to the area from Liege. The works at Sunderland were demolished in 1917/8 and replaced with Scotia Engine Works.

The Assembly Rooms were to the west of Holy Trinity and are shown on Rain’s Eye Plan with a range of buildings to the south, a square or green in front, and a wall and railing with a gate to the east. A later range of buildings was built on the north side. Both ranges were almshouses. In the 18th century the assembly rooms were taken over by the Trustees of the Sunderland Muster Roll as a charity for disabled sailors and their dependants.

The first purpose-built Customs House was on Bishopwearmouth Green. It was replaced in the 17th century by another in Low Street, established in 1784 and shown on Rain’s Eye plan.

In around 1715, when the new parish boundaries of Sunderland were drawn up, a house was built on No. 4 allotments on the Banks, and used for many years as the Customs House.

Rain’s Eye Plan shows The Hospital House, and a set of almshouses which were built in 1727to the east of St. Michael's church.

Spa well was located on the Town Moor, 70 yards west from the moor edge. In 1718 it was covered with a brick arch. The Spa remained until the beginning of the 18th century when it was washed away by the sea.

Baptist Chapel built in 1798. In 1856 it was Particular Baptist. Brick with stone quoins and dressings.

This Jewish Synagogue in Vine Place was associated with a burying ground at Hetton Staiths.

In 1790 a Wesleyan Chapel was built at the foot of Sans Street. It was enlarged in 1809 and 1824 with east and west wings as dwelling houses for preachers. Seated 3000. Congregation moved to Ashbrooke Road 1888, then became city centre mission. It was altered and refronted in 1903 and closed in 1963 when the congregation moved to Park Road.

In 1758/59 a chapel was built at Number's Garth, this is shown on the Eye Plan as a Methodist meeting house. Closed 1793 - congregation to Sans Street.
