Nymph Pit (Coal) is shown at this location on the 1st edition Ordnance Survey plan, but is not shown on the 2nd edition plan, indicating that it was out of use by c.1895.

Maria Pit. Owned by the Throckley Coal Company, who also owned Throckley Colliery (HER 4224). Closed in 1953.

Throckley Brick and Tile Works. Marked and Throckley Firebrick and Clay Retort Works on the 2nd edition OS mapping {1}. Mr W Stephenson had established a brick and tileworks near the Maria coal pit by 1849, making firebricks, common bricks, quarls, field drainage tiles and soles. Early handmade firebricks were marked “W.S.& Sons, Throckley”, or “Stephenson, Newcastle”. In the 1920s a new grinding plant was installed and two new brick machine presses. The brickyard eventually had 34 Newcastle-type kilns. In 1951, these kilns were replaced by a 20-chamber Staffordshire transverse-arch kiln, and produced six million bricks per year. A tunnel kiln was built in 1965 and the works modernised by the Northern Brick Company. The Throckley works pioneered the manufacture of through-coloured grey facing bricks from which the Mitford range of bricks developed. The Throckley yard is the only survivor of a group of 26 brickworks that were owned by the National Coal Board in 1947. In 1973, Gibbons (Dudley) Ltd took over the remaining nine brickworks and by 1977 only Throckley and Cramlington were still working.
Dates: 1857 – 1986 (Stephenson’s Yard, Throckley)
Manufacturer from 1857-1947 was W Stephenson and Sons.

William Stephenson's Throckley Brickworks were said to be the site of the last surviving Dandy Cart (a four-wheeled truck which was horse-powered on the flat or up inclines, but the horses 'rode' on the truck downhill). It was used at Throckley until 1907. The horses pulled the wagons loaded with firebricks and furnace lumps, from the brickworks to the level crossing at Throckley, then rode the Dandy Wagon downhill to Spencer's Steelworks at Newburn, then pulled the wagons to Lemington Staiths. Once emptied, the wagons were pulled back to the brickworks by the horses.

Wardle Pit (Coal) is shown at this location on the 1st edition Ordnance Survey plan, but is not shown on the 2nd edition plan, indicating that it was out of use by c.1895.

Rye Pit (Coal) is shown at this location on the 1st edition Ordnance Survey plan, but is not shown on the 2nd edition plan, indicating that it was out of use by c.1895.

Bean Pit (Coal) is shown at this location on the 1st edition Ordnance Survey plan, but is not shown on the 2nd edition plan, indicating that it was out of use by c.1895.

Meadow Pit is shown on several 18th century estate maps of Throckley contained in the collection of Northumberland Record Office. An undated (but pre-1865) plan of ‘The Throckley Estate and workings in the Engine Seam belonging to Greenwich Hospital’ shows the extent of the underground workings of Throckley Colliery. It shows that the colliery was working the Engine seam (better known as the Low Main Seam) by pillar and stool workings. The site has been levelled.

The exact dates of operation of this pit are not certain, but it is known that it had started by 1769. Hill Pit is shown on ‘A Plan of the enclosed lands in the lordship of Throckley in Northumberland’ (Northumberland Record Office), dated to 1769. On a ‘Plan of the Inclosed lands of Throckley’, dated 1781, the shaft of Hill Pit is marked but not named at the north end of a large sub-oval enclosure, suggesting that it has closed by this time. An undated (but pre-1865) plan titled ‘Plan of Throckley Estate and workings in the Engine Seam of coal situated in the parish of Newburn belonging to Greenwich Hospital’ marks 'the Hill' as an isolated and evidently abandoned shaft. Hill Pit is shown on the 1st edition Ordnance Survey plan of 1858 as wooded, suggesting that it was disused by this time.

Drove Road, Throckley appears on a 1769 ‘Plan of Enclosure Lands’ (Northumberland Record Office), and the name is marked on the 1st edition Ordnance Survey plan as if it was the name of the road rather than its function. The present Drove Road is still a broad road and may be a medieval or earlier route for leading livestock to and from Throckley Fell, an area now north of the A69. A Roman surface was recorded in excavations in 2002 on Hexham Road in advance of installing renewed water mains. This raises the possibility that Drove Road may be of even greater age, perhaps originally representing a track leading through the milecastle.

Dayhole Pit (Coal) is shown at this location on a map of 1774 and the 1st edition Ordnance Survey plan, but is not shown on the 2nd edition plan, indicating that it was out of use by c.1895.
