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.

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.

Smithy identified on the First Edition Ordnance Survey plan 1856. Recorded up to 1939 and still shown until 1968 but not labelled. Demolished by 1974.

Recorded but not labelled on Greenwood 1820. Named on First Edition OS 1862 shown as a single range N-S along Hylton Lane. Current building is rendered with a pantile roof. It has been extended along Washington Road to form an L-shape, the later addition having a hipped roof.

Recorded but not labelled on Greenwood 1820. This farm along with Elliscope (HER 960) and Hylton Grove (HER 6776) farm are shown on the 1840 tithe plan as one holding known as the Hylton Bridge Estate owned by John Dutton. Surviving stone buildings are likely to date from the late 18th-early 19th century or earlier.
