Coal Exchange, London

's New Picture of London and Visitor's Guide to its Sights Coal had been imported to London by sea since at least medieval times. A coal exchange was established in 1770 on Thames Street in the City of London, near the site of Smart's Quay and close to Billingsgate Market; the main trades at Billingsgate Dock were fish and coal. The market was established by the main coal merchants as a private body to regulate and control the trade of coal in the capital. A new building had been built in 1805, with a recessed classical portico supported by small Doric pillars and triangular pediment above, with stone steps leading to a quadrangle within. Under the control of the City Corporation from 1807, the Coal Exchange became a free and open market, regulated by various Acts of Parliament, including Acts in 1831, 1838 and 1845. At this period, London was heated almost entirely by coal. By 1854, approximately 3.5 million tons of coal was being transported each year from the coalfields in Northumberland and Durham to London. Historically, coal taxes, payable on each chaldron of 35 bushels or the imperial ton) were charged by the City based on volume measurements. A public measurement system, called metage, prevailed. Officials, called sea meters, measured the coal delivered from ship to barge; others, called land meters, measured coal into standard sacks at the quayside. Monies owing to vendors, and to the Crown and City for taxes, were calculated with reference to the metage. A coal duty of 4 pence was confirmed by James I, with a duty of 8 pence more added under William III and Mary II, and an additional 1 pence added to fund the construction of the new Coal Exchange. By 1845, a petition was made to build a new exchange, and the City Clerk of Works, James Bunstone Bunning, produced a design, which was displayed in the form of an architectural model at the 1847 Royal Academy Summer Exhibition. Construction started in December 1847 and the new Coal Exchange was formally opened by Prince Albert on 30 October 1849. The Lord Mayor and City MP, James Duke, was made a baronet in honour of the occasion. ==Description==

The new Coal Exchange was built on the north side of Thames Street, on the east side of its junction with St. Mary-at-Hill, with four floors. The south and west fronts, facing the streets, were built in Italianate style from Portland stone, with four floors, measuring wide and high. At the southwest corner was an unusual high semi-circular portico with Doric columns and entablature, surmounted by a tower of Portland stone high, with a conical roof topped by a gilt ball. Within the tower was a staircase providing access to the upper floors. The ground floor portico provided access to an entrance vestibule leading to a large central circular vaulted hall. The central rotunda was in diameter, with a wooden floor inlaid with a large mariner's compass. The rotunda was covered by a glazed cast iron dome with its centre above the ground, held up by 8 cast iron piers, supported by 32 ribs 42 ft 6in long. The dome design was based on that of the Bourse de commerce of Paris by François-Joseph Bélanger and François Brunet, completed in 1811. The dome was decorated with "Raphaelesque" encaustic panels by Frederick Sang on a coal-related theme, depicting fossils of ferns, palms and other plants, and images of collieries and mining operations, and views of North Shields, Sunderland, Newcastle upon Tyne and Durham together, with cast iron decorative features. The piers also supported three tiers of cast iron galleries which opened on to offices around the exterior of the building which were occupied by coal factors and other agents and merchants connected with the coal trade. ==Demolition==

The building suffered some damage in the Second World War, and it ceased to be used as a coal exchange after the war when the coal industry was nationalised. It was then used as offices, but the City of London did not proceed with plans to refurbish the building in the 1950s because its demolition had been suggested to allow widening of the road from Blackfriars to the East End, and it became progressively more dilapidated. Nonetheless, in the 1950s, Professor Henry-Russell Hitchcock described it as "the prime city monument of the early Victorian period". In September 1956, John Betjeman (a founding member of the Victorian Society and a passionate defender of Victorian architecture) gave a speech to the Society for the Protection of Ancient Buildings in the rotunda of the Coal Exchange to argue for its preservation. It became a Grade II listed building in 1958. A letter published in The Times and signed by Walter Gropius, Sigfried Giedion, Josep Lluís Sert and Eduard Sekler described the Coal Exchange as "a landmark in the history of early iron construction". Various alternatives were proposed. The Georgian Group and the Victorian Society both favoured preservation of the Coal Exchange, even if that meant that the "very dull, plain and ordinary" rear parts of the nearby Grade I listed Custom House (then the headquarters of HM Customs & Excise) were removed. Others suggested a scheme in which a walkway would be added in arches under the Coal Exchange. There was also a suggestion that the dome could become part of the new Royal School of Music in the Barbican, or shipped to Australia to become part of the National Gallery of Victoria in Melbourne, but funds were not available. Despite campaigns and protests, it was demolished in November 1962 to make way for a "vital" widening of Lower Thames Street. The demolition of the Coal Exchange was described by author Hermione Hobhouse as "one of the great conservationist horror stories". Cast iron dragons which were mounted on the eaves parapet above the entrance to the Coal Exchange were preserved and were erected as dragon boundary marks in October 1963 in Temple Gardens on Victoria Embankment. ==See also==
