20, Cannon Street and Old Peoples Day Centre, Eagle Street

20 Cannon Street, including the Old People's Day Centre on Eagle Street, is a former Manchester and Liverpool Bank built around 1865, now used by the Environmental Health Department. The building is constructed of ashlar stone with a slate roof.

The main facade facing Eagle Street features a single-storey flat-roofed pavilion on the left, a gabled porch and entrance hall, and a two-storey block on the right, all designed in the Italian Gothic style. A modillioned cornice runs around the entire structure, with the pavilion and porch displaying a saw-tooth pattern below it. The pavilion's parapet rises above the porch to create a shaped gable that displays a carved coat of arms. The center of the pavilion projects forward to form a bay with a triple window. To the right of the porch, the two-storey block has four windows on each floor. The ground floor windows have a round intrados and pointed extrados for each light, with roll-moulded jambs and heads, and crocketed imposts. The first-floor windows are segmental-headed sashes with linked stilted hood moulds and a prominent cornice. Various medallions are positioned between the window heads on the ground floor, with those on the right return wall inscribed "M & L" and "DE". The rear wing is constructed of rock-faced stone in a similar style and originally served as domestic quarters.
