3 Highgate Terrace

3 Highgate Terrace is a group of four three-storey, one-window red brick cottages, with a two-storey, two-window former gaol on the right end. The cottages feature a renewed slate roof, boarded eaves, and modern brick chimney stacks, along with a black painted plinth. They have small pane sash windows with voussoirs, with 15-pane windows on the second floor and 20-pane windows on the first and ground floors. The entrances are camber headed with boarded doors. Between cottages 3 and 4, there is a round arched entry to a tunnel passage, now fitted with a metal door and a plain fanlight.

The former gaol has an old slate roof with a brick stack and part slate hung. It features a 15-pane sash window on the first floor and a 20-pane window below, next to a similar entrance. The left end is largely shale, rendered at the top where a weaving loft door has been blocked up. The right gable end is pebbledash, while the gable end of the gaol is slate hung and has an attached boarded lean-to shed. A colourwashed passage leads to the shale rear elevation with brick dressings, cambered voussoirs, and modern casement windows. There are brick privy lean-tos for cottages 1 and 3, and a later one for cottage 4, along with small cellar windows. Boarded loft openings conceal windows. The rear of the gaol is constructed of shale above rubble and features small pane metal frame windows.

The second floor of the building is open throughout and served as a weaving loft. Cottages 2 and 3 have been combined into one house. The interior of the gaol retains two cells with barred windows, where chartist rioters were held, and accommodation for policemen is located above.
