Telephone Kiosk outside 4 Obre Avenue, Clontylew Road, Portadown BT62 1RT

A K6 model telephone kiosk of cast iron construction, located on a grass verge in front of No. 4 Obre Avenue, Clontylew Road, Tartaraghan, a small hamlet in The Birches south of Lough Neagh. The kiosk was installed sometime between 1954 and 1964, as it does not appear on the 1954 Ordnance Survey map but is present on that of 1964.

The structure is built to Sir Giles Gilbert Scott's standardised design of 1935, created to celebrate the Silver Jubilee of King George V. It is a square-plan, freestanding structure standing approximately 8 feet high and 3 feet wide, constructed from cast-iron sections bolted together and painted red. The symmetrical design sits on a concrete base and features a shallow cast-iron domed roof carried on moulded pediments. The four elevations are largely symmetrical, with glazed panels to three sides and a solid blank back panel to the north-east (rear). Beneath the shallow roof are cream-coloured opaque glass rectangular signs reading "Telephone" on the north-west and south-west sides (now faded) and on the north-east and south-east sides (replaced). These signs are surmounted by a raised St Edward's Crown moulding on each elevation, introduced following the coronation of Queen Elizabeth II in the mid-1950s.

The south-east and north-west sides are infilled with replacement perspex panels, while the south-west side retains two middle panels infilled with painted plywood. The original glazed panels have been lost throughout. A foundry plate is visible beneath the rear panel, though overpainted and unreadable; other kiosks of this era were manufactured by the Saracen Foundry in Glasgow.

The K6 was the most successful and populous telephone kiosk design introduced in Britain. Designed for mass production and distributed from 1936 onwards, some 60,000 examples were placed across the country. Approximately 8,000 were installed under the 1936 "Jubilee Concession", which allowed towns and villages with a post office to apply for a kiosk. A further 1,000 were installed over 12 years under the 1937 "Tercentenary Concession" celebrating the Post Office's 300th anniversary, with local authorities paying a five-year subscription of £4. The K6 represented the development of Scott's earlier telephone kiosk models, the larger K2 (introduced 1926) and K3 (1929).

The kiosk is located within visual range of the nearby listed vernacular public house, Lawson's Bar (now called The Head o the Road), and greatly adds to the distinctiveness of the settlement of Tartaraghan. Despite the loss of original glazed panels and alterations to the glass infilling, this remains an important example of an iconic piece of street furniture that is now increasingly rare.
