The Grey Horse. Two storey, three bay frontage facing south and a rear wing return at the east end. The front is rendered and whitewashed and has a central doorway with a pair of 16 pane sashes to the side. Possibly mid 19th century although the rear wing (roughly coursed squared limestone) looks older.

Saw mill shown on the First Edition Ordnance Survey plan 1862 between Low Lambton Staithes and Low Lambton Drops. It features a saw pit and crane as well as the main saw mill building, plus waggonway sidings connecting it to one of the sprouts or drops on the riverbank. Probably out of use by the end of the 19th century.

Furthest upstream of three staiths. Shown in the Penshaw Staithes area on Burleigh and Thompson's 1737 plan . Out of use by 1775. The staith belonged to Sir Edward (or Meaburn) Smith. The Smith family had leased Morton Colliery two miles to the south since 1698.

Coal pit (two shafts) shown in Keelman's Field, Penshaw on the 1775 Tempest estate map as two adjacent bell pit shafts. Formed part of Pensher Colliery. Laidler's Pit labelled on Bell's Coalfield Map 1843 but not on the 1st edition OS. May have actually been out of use by 1820 superseded by the D (HER 3099) and E pits (HER 3107) at White Field and Wharton Row (later Shiney Row).

Pit shown on the 1848 Tithe plan and subsequent OS plans.

Fishery in the Wear at Shiphaught recorded in medieval IPMs as held by the Lamptons.

Sinuous boundary forming southern limit of Penshaw and South Biddick townships shown on maps from 18th century onwards. Preserved in small part within the modern urban townscape.

Manorial watermill held by the Bassets and then the Carlisles repeatedly referred to in medieval documentary sources, notably Bishop Hugh du Puisset's charter of c.1170/80 and Boldon Book. Mill race and dam shown but not labelled on 1775 plan of Penshaw. Buildings now demolished but the position of the broad mill race or Mill Dam (infilled) can be traced on the ground marked by a dense grass extending N-S on the west side of the burn. Dated C12th.

Site of the former Londonderry School.

St. Hilda's School opened on 1st June 1903. It is constructed of red brick and is a typical early 20th century school. The internal arrangement of some areas have been altered. Two extensions (also in red brick) have been constructed to the eastern and north-western gable ends. The majority of the windows that face the central corridor are still intact. There is a noted absence of coving, picture rails and dado rails and original features including the fireplace surrounds and wooden block flooring have been stripped out. The building was photographed by URS in 2014 ahead of the proposed redevelopment of the site.
