The Castle Tap, 120 Castle Street

The Castle Tap is a public house, likely rebuilt in the mid-19th century on the site of an earlier coaching house. It was formerly known as the Horse and Jockey Public House. The building is constructed of red brick in a Flemish bond pattern, with a stucco cornice and plat band, and glazed red brick detailing around the door surrounds. The roof is covered in slate.

The building occupies a roughly rectangular plot, running north from Castle Hill at the southern end. The main, two-storey section is L-shaped, with a rear projection along the western boundary. Later single-storey extensions have filled in the L-shape and expanded the building's footprint into the rear yard.

The main elevation on Castle Street is two bays wide, with the eastern bay slightly recessed. The western ground-floor bay features a large fixed window set under a flat arch of gauged brickwork. The eastern half contains two tall, narrow doorways, separated by glazed brick pillars. Each doorway has a half-glazed two-panelled door, topped by an etched-glass fanlight, a moulded and rendered architrave, and a further rectangular fanlight also containing etched glass. The first floor has two six-over-six sash windows with horns, set within large rectangular recesses with gauged brickwork flat arches. A plat band runs just below the first-floor sills, continuing onto the eastern elevation and matching that of the adjacent property at 122 Castle Street. A broad cornice projects from the southern elevation, also matching the adjacent property.

The building has been extended to the rear three times. The northernmost extension, adjoining the original red-brick section, has a flat roof. The two southern extensions, of different dates, span the width of the plot. The eastern of these appears to be older, constructed of red brick with a rendered lower half and a mono-pitched roof sloping north. The south-western extension is of late 20th or early 21st century date and has a flat roof. The rear yard is paved.
