Ordnance Survey first edition of 1862 shows Painshaw Colliery, Whitefield Pit with brick kilns within the colliery. Opened 1830. E Pit was at NZ 322 525, Lambton Pit (which was opened in 1792) was at NZ 319 533, New D Pit (opened 1832) was at NZ 322 533. The colliery was owned by Lady FA Vane Londonderry, and leased/managed by George Elliot & Co. Extensive records in DRO. Possibly closed in 1879. The main site has recently (2014) had houses built upon it. The ventilation fan house (marked on the second edition OS plan) was rebuilt when the structure was converted into two houses. The original west frontage survives. Whitefield cottages are much rebuilt but are shown on the 1815 estate plan.

Painshaw Station on the North Eastern Railway (HER ref. 2625) is now disused and the track has been diverted, so no longer passes the platform. The line is used for goods traffic only.

New Painshaw Pit, sunk in 1792 and closed 1833. Depicted but not named on Bell's coalfield map of 1843. Tithe plan labels this area as 'waggonway, houses, gardens, pit and waste'. Site of explosion in 1822.

Historic Ordnance Survey map evidence shows the position of Painshaw Engine on the Londonderry Wagonway (HER ref. 3081).

Cross Rigg Quarry. Leased by J & W Lowry Ltd. between 1895 and 1931. Photos and maps held at TWAS. Also known as Dyson's Quarry. Located midway between Old and New Penshaw.

In 1840, shortly after the death of John George Lambton, first Earl of Durham (1792-1840), (and Governor-General of Canada and Grand Master of the Order of Freemasons), a committee was established to build a monument paid for by public subscription (£6000), in his memory. Penshaw Hill was selected for the site of the monument, and the design of a Grecian temple (contemporary accounts say it was based on the Temple of Theseus at Athens) by John and Benjamin Green of Newcastle, was adopted. Built by Thomas Pratt of Sunderland. The dimensions of the structure are 100ft (30.5m) length, 53ft (16.2m) width and 70ft (21.3m) height. 4 x 7 fluted Doric columns. The foundation stone for the monument was laid 28th August 1844 by the Earl of Zetland, watched by over 10,000 spectators. The monument has been the property of the National Trust since 1939. Original plans were to roof over the pediment to adorn the monument with an equestrian statue - this was never done of course. Pevsner - subscribed for and dedicated by the inhabitants of the county to John George Lambton, first Earl of Durham, the great liberal politician and first Governor of Canada, died 1840. Erected in 1844. John and Benjamin Green based the design on the Theseum at Athens. Half its size, Greek Doric (but the columns are unfluted with a spiral staircase in one), of seven by four columns with entablatures and pediments but no roof or walls. The columns stand on a stylobate but there are no steps. From a distance, especially the east, the monument looms as an apparition of the Acropolis under hyperborean skies. Walkway around the parapet - closed in 1926 after a fatal fall. At the base of the foundation stone there is a National Trust plaque which replaces an eroded verse that was carved into the monument. The monument and woodland is owned by the National Trust. The hill may be the site of an Iron Age hillfort (HER 16664) although no definate dating evidence exists.

Painshaw New Winning, Coal Pit. Marked as Old on the 1st edition OS mapping, so probably disused by 1858. A shaft with adjoining spoil, plus a rectangular pon ddepression are depicted on the map (possibly an abandoned reservoir?), but no buildings. Presumably formed part of Lambton's Pensher Colliery.

Small limestone quarries on SE and SSW side of Penshaw Monument. Marked as Old on the 1st edition OS mapping, so out of use by 1858. The precise definition of these features is unclear due to poor copy of the map.

Penshaw Hill Quarry shown on the First Edition Ordnance Survey 1856 but disused by 1898. Large quarry with some evidence of bedding plans, and producing building stone as well as lime for burning. First edition map shows lime kiln in the centre.

This Sand Pit is marked as ‘Old’ on the 1st edition Ordnance Survey plan, indicating that it was probably out of use by 1858.
