Summary
A gas street light comprising a column probably dating from the late C19, with an extension shaft and Rochester-type lantern probably installed around 1930.
Reasons for Designation
The lamp post outside 2 Dean Stanley Street is listed at Grade II for the following principal reasons: Architectural interest: * for the well-crafted, decorative column in cast iron, which is a good example of historic street furniture;
* for the design of the Rochester-style lantern, a popular and enduring style of lantern. Historic interest: * as a good example of a historic gas lamp column probably dating from the late C19 with an early C20 lantern. Group value: * as part of an adjacent set of historic lamp posts on Dean Bradley Street, Dean Stanley Street and Dean Trench Street and a wider group across other key streets within the Smith Square area.
History
Gas street lighting first appeared in London in June 1807 when Frederick Albert Winsor gave a public demonstration of gas lights in Pall Mall. The expansion of the railways coinciding with the development of urban gas works in the 1840s facilitated the proliferation of cast iron lamp posts with open-flame gas burners across the capital in the mid-C19. This feature of industrialisation was seen to contribute to London’s international standing and also facilitated the development of modern urban living, increasingly unconstrained by daylight hours. Electric street lighting was introduced from the 1880s and the gas industry responded by making technological improvements to gas lights, principally the incandescent gas mantle in 1896. This significantly increased the efficacy of gas light, but it was not until the introduction of the inverted gas mantle in 1905 that gas street lights were really able to match the efficiency and brightness of the rival electric carbon filament lamps. In the 1920s and 1930s, many gas lamp posts in Westminster were upgraded with new lanterns fitted with inverted mantles. Gas remained an important source of power for street lighting as late as the mid-C20, and smaller numbers of lamps have continued to run on gas into the early C21. The Smith Square area was laid out in the C18 and is named after Henry Smith who owned the land to the north. At the centre of Smith Square is St John’s Church, 1713-1728 designed by Thomas Archer. To the north, early C18 terraced houses are located on Lord North Street, Cowley Street and Barton Street. Great College Street includes a mixture of C18 houses and early C20 houses and offices. This pattern is also seen on Gayfere Street. Tufton Street includes early and mid-C20 offices. To the south, Dean Trench Street and Dean Bradley Street include examples of mid-C20 houses and offices. Neoclassical mid-C20 offices are also located on Dean Stanley Street. Together, the Smith Square area is a clear illustration of a unified C18 development punctuated by later C20 buildings. A historic image indicates that it is probable that the position and configuration of the lamp post outside 2 Dean Stanley Street has not changed since at least the 1970s. The ornate design of the column suggests it dates from the late C19. The extension shaft to the top of the column was added later to raise the height of the lantern and improve light distribution, possibly around 1930 when the present Upright Rochester lantern was installed to replace an earlier, outdated lantern. Rochester lanterns were the 'storm-proof' version of a series of lanterns introduced from the early C20 and went on to become one of the most popular designs of shadowless lanterns.
Details
A gas street light comprising an ornate column probably dating from the late C19, with an extension shaft and a Rochester-type lantern probably installed around 1930. MATERIALS cast iron lamp post with a glazed lantern of iron, spun copper and enamelled steel. DESCRIPTION: the lamp post consists of a column with acanthus leaves at the base and floral mouldings, an extended fluted shaft and topped with an Upright Rochester lantern. The lantern has a circular drum and rain-shield of copper above an inverted, six-mantle burner in a teardrop-shaped glass enclosure with a drainage hole to its base an enamelled steel reflector. This whole assembly is suspended in an iron cradle with two curved uprights projecting from the clock box. These uprights have lost their original decorative ironwork scrolls typical of earlier inter-war Rochester lanterns.
