Quarry, marked as Old on the 1st edition OS mapping, so was probably out of use by 1855.

Limestone Quarry and Lime Kiln, both as marked Old on 1st edition OS mapping, so was out of use by 1855.

Horne and Scott's Bottle Works, by the west side of the Wearmouth Bridge. This was originally called Bishopwearmouth Glasshouse. It was opened in 1765 by John Hopton to produce Table Glass, it was subsequently run by Hilkiah Hall and in c.1809 was taken over by Laing, Horn, Scott and Company, producing bottles and plate glass. It closed in 1877 and was demolished to make way for a railway bridge.

Marked on the 1st edition OS mapping as "Ayres Quay Road Steam Mill (corn)" {1}.

Lime Kiln, on the north side of Rector's Park.

The Lambton Wagonway. Its northern terminus was at the Lambton Drops, (SMR 2832), on the Wear. Its southern end lay outside the county. This line was built in 1815 by the Nesham family to replace an earlier one from Philadelphia to the Penshaw Staiths. The Lambton Wagonway was the site of an experiment by William Brunton in 1813. His "Mechanical Traveller" machine worked on the part of the line between Margaret Pit (HER 3126) and West Herrington throughout the winter of 1814. It obtained progressive motion by an ingenious combination of levers which acted like walking legs. But on 31st July 1815 a boiler which had been fitted to it at Philadelphia exploded, killing 16 persons and injuring 40. Is this the same stationery engine which was said to have been torched by Keelmen in 1815? The line was sold to John Lambton in 1822. The section between West Herrington and the Grindon Engine was realigned c.1831. The line was finally abandoned c.1870 {1}.
In 2018 an archaeological excavation exposed a 20m x 4m section of the Lambton wagonway. Excavations exposed the multi-phase development of the wagonway and impressions of timber sleepers and a stone sleeper at a depth of 1.15m BGL (64.43m AOD). Five different groups of sleepers were identified. The narrowest consisted of single rail sleeper impressions an average length of 0.83m. The widest wagonway excavated were designed to carry two rails and had an average length of 2.08m. No wagonway ditches were identified. Five timber pins or pegs 9-14cm in length and 1.5-4cm in diameter were also excavated.

Lambton Drops, the northern terminus of the Lambton Wagonway (HER 2833). The railway was built in 1815 to bring coal from inland to the mouth of the river where it could be loaded onto sea-going colliers. Prior to the construction of the railway, large steam powered crane-like devices, designed by either William Bell or William Burlison, were constructed to lift the tubs of coal from the barges which had brought the coal down river, into the colliers. A complex of buildings and an incline is shown on Rennie's map of 1819. Major modifications occurred from 1865 to 1890s. A programme of tunnel building rerouted the Lambton railway - the railway supplying Lambton Drops approached the staiths from the west through a tunnel which emerged into Galley's Gill. The number of drops increased as did the complexity of the rail tracks supplying them. The Lambton drops closed in the 1960s and the railway dismantled in 1967. Elements of the facilities remained in situ until 1972 when the Riverside Park was created. A watercolour painting survives of the staiths in the 1930s.

A Coal Depot, located between the Hetton and Lambton Drops. It is not clear from the 1st edition OS how it related to these sites.

Coal Depot, probably related to the Lambton Wagonway and Lambton Drops, (SMR 2832 and 2833 respectively).

Shown on Meik and Morgan's plan of Sunderland 1851. Not labelled as gas works by 1897 Second Edition plan. Included gasometer (no longer present by 1897).
