'The Harbour Inn' Public House, 4 South Promenade, Newcastle, Ballagbeg, Co Down, BT33 0EX

The Harbour Inn is a large and unusual two-storey public house dating from around 1905, situated on the east side of the south end of South Promenade in Newcastle, overlooking the shore to the south of the town centre. The building appears to have originally been constructed as a house and shop.

The front façade, which faces roughly west, is asymmetrical and dominated by two distinctive oversized Jacobean style gables. The left gable contains a central timber panelled door to the ground floor with a blocked fanlight recess with segmental arched head, flanked by a pair of openings with similar arch heads. The opening to the right has been converted to a doorway; the one to the left retains its sash window. To the right of the central doorway are another pair of windows, followed by a single sash window positioned between the gables. The right gable features a broad flat-headed doorway with double doors and a group of three flat-headed sash windows. All ground floor openings are linked by a moulded string course that continues around the heads of the openings, with moulded keystones to those with segmental heads. The first floor of the left gable has three evenly spaced windows with semicircular heads, the centre one being taller with a sash frame; the outer windows have modern frames. The first floor of the right gable has two flat-headed windows with modern frames. The front façade is finished in plain render and painted.

The north façade contains a doorway matching the centre of the left front gable but with a more recent partly glazed door to the left. To the left of this are two windows with segmental heads linked by a string course. A large internally illuminated sign is positioned between windows to the right, with steps and a low wall leading to the doorway. This façade is finished as the front.

The south side of the building features a single-storey gable section that formerly served as a store but has been converted into a small restaurant, obscuring the ground floor of the main building. The exposed upper floor has a large modern window to the left and two smaller windows with modern frames to the centre and right. This portion is finished in pebbledash.

The rear façade comprises two gables linked by a single-storey flat-roofed section. Both gables contain a mixture of window and door openings, mostly modern. The left gable has a much shallower pitch than the right. The rear façade is finished in rough cast and painted.

Both main sections of the roof were originally gabled, though the southern section is actually hipped to the west side. Both are mainly covered in natural slate, though the north side of the northern section has asbestos slate and features three large gabled dormers added recently. The other side of this section has at least three modern rooflights and a tall rendered chimney stack. The rainwater goods are PVC. A modern low rendered wall fronts the property.

The building has been substantially altered since its construction. Originally, it contained large roundel windows to the first floor of each gable and a shop front to the southern gable. The openings to the front gable have been significantly modified over the years. The building functioned as a private house and shop from around 1905 until it became a public house in the mid-1970s, a use it has retained since.
