During excavations in 1973, a post hole, 1m square was found cut into the natural boulder clay. In it was an oak post and a sherd of late C2 Roman coarse pottery. Dated C2.

During excavations in 1973, a C16 wattle and daub wall on a low stone wall was recorded. It was aligned east-west and had a 25 x 10cm oak beam on top. The retaining wall of All Saints Churchyard had collapsed in 1814 and this perhaps explains the presence of tombstone fragments and human bone and teeth in this trench. On the south side of the trench, the north end of a medieval building of unknown date was recorded cut into the natural boulder clay. Above the wattle and daub fence was a layer of clay into which a fence of close-set birch uprights had been set following the line of the first wall. Above this was a layer of C17 rubbish, again sealed by a layer of clay. When the trench was extended to the east, a C17 ditch was found, and to the west a fence of oak uprights 1m apart to which planks of oak had been nailed. Dated C16th.

A well was found in 1881 on high ground 25 yards south of Wall Knoll Tower (HER 1562). It was rectangular and 4 feet 10 inches x 6 feet 8 inches in plan, covered by a brick vault and with stone lining. Part of it was covered by a circular stone like a millstone (5 feet in diameter and 9 inches thick) with a square hole in the centre. An entrance had been left in the arched roof of the well and in it were lengths of cast iron piping with flanged joints. The oak timber stays were black with age. A culvert 'of curious construction' led towards the well. It was formed with flat stone slabs on the base with a semi-circular arch 18 inches in diameter above it. The stones were dressed on the inside and outside and Holmes considered them to be reused.

In 1881 on Wall Knoll (HER 6567) near the monastic buildings (HER 1425 and 1426) and the fine rich soil of the monastery garden, several human skeletons were found.

Grainger's workmen had been digging up the foundations of some old buildings, and an ancient burial ground where the new markets and streets were intended to be laid out in the Nuns' Field. They found a stone coffin, lead coffins, and the decayed wood of others, 3-4' deep, most embedded in clay. They were clearing a lot of bones, thought to indicate the regular burial place of the nuns of St Bartholomew's Priory. Several entire skulls were supposedly found, together with the fragment of a tablet which has been transcribed. The report gives no precise location.
[See the reference to stray finds from the 1834 campaign which gives more detail of the inscription in Richardson 1844, 200 (Event Rec. No.475)].
[Caution: the incident was reported second-hand in the newspaper, and may be classified as circumstantial evidence.]

Excavations in 1990 found that ballast dumping in C13 had created a linear embankment of the foreshore, south of the natural shoreline. The embankment was made up of water-worn boulders of carboniferous limestone, pieces of chalk and flint. Pottery found above the dumped ballast suggests a date of construction within C13. In the C14 the area between the artificial embankment and the original north river bank was infilled with ballast sand. The embankment continued to be raised in height and more ballast sand dumped behind it. There was evidence of limeburning on the shore - an ash and mortar layer, then limestone and chalk dumps to a height of 0.60m upon which a southern row of 4 lime kilns were built. The kilns were tied together by a sandstone frantage wall. Great quantities of waste was produced and dumped to the south. 3 further kilns were built. A revetment wall and possible wharf for offloading limestone and chalk to charge the kilns. The downward slope of The Swirle was infilled with limekiln waste, pottery, lopped branches and leather offcuts and pieces from shoes (92 pieces of cow-hide sewn with flax threads). Pottery evidence suggests that limeburning took place before the early C14 and until the third quarter of the C14. Archaeomagnetic dating suggests up until c. 1380-1400. After the kilns were demolished there was a massive landfill operation using domestic and industrial refuse (including C14-C16 pottery). In C17 the site was terraced and a north-south revetment wall built. Structures including a series of floors, an external hardstanding of cobbles and pebbles and a pit containing Tudor greenware were built onto the terraces cut into the ballast. These were demolished in early C18. Dated C14th.

In a trench excavated by the North of England Excavation Committee in 1928 on the projected line of Hadrian's Wall a large flat circular stone was recorded at a depth of 9 feet. The stone was 4 feet in diameter and was shaped like a mill stone with a central hole 6 inches in diameter. It was surrounded by a circle of wooden piles. NEEC thought it was post-Roman.

Built in 1814. Shown on Thomas Oliver's plan of 1830. Built over by a police station (HER 11966) in 1885.

Shown on Ordnance Survey first edition. Foundation stonework and a brick-lined well were found in excavations in 1991.

During excavations in 1989, phase 6 recorded accumulated deposits against the town wall, sloping towards the river, covered by a thread spread of white mortar. The southern section was truncated by a structure of large masonry used to revet depoists to the north of it. To the south a large inlet or tidal dock had been created by removing a depth of over 1.25m of deposits. Associated finds were C18. This may be a barge house, referred to in the early C19. Phase 7, showed that in C19 the inlet was reduced in size by a timber revetment, which held back a thick sand and pebble layer. Post 1823. The barge house was demolished thereafter. Botanic remains showed that the site was not completely waterlogged although the lower levels were regularly inundated by the tide.
