The Henry Pit was an 18th century working at Walkergate, opposite the hospital and just north of what became the Newcastle & North Shields Railway. It was also the terminus of the waggonway from Walkergate down to Low Walker to meet the staiths on the Tyne. It was a fair size given its age, with at least 3 ground level ancillary buildings surrounding the single shaft (as in those days, only one access point was required. It is still likely the Walker pits connected).

The Henry Pit remained so as a coinage for the area. Despite it closing in the 1840s, folk were still living at the Henry Pit site in the 1870s and remained referenced into the 1890s. The inhabitants petitioned to have a supply of water and gas in 1874. The houses still belonged to the Walker Colliery Co, and they contested their duty to provide it. In 1891, a man died in the area who lived at the Henry Pit. The fact the term still survived is similar today to places like Boldon Colliery and Easington Colliery.

A detailed plan (TWAS D/NCP/19/3) of the workings of Walker Colliery drawn after 1796 includes the Henry Pit and graphically shows that intensive pillar and stall workings extended under the site now occupied by Walkergate Hospital. In the early19th century Walker Colliery had 10 pits working, including Henry Pit. As early as 1817 it was reported that Henry Pit was close to exhaustion. It was disused by 1843 and is marked as such on the 2nd edition Ordnance Survey plan. - Sitelines
