Nottingham Exchange

in 1830 and now in Nottingham Industrial Museum The Nottingham Exchange was erected between 1724 and 1726 replacing a shambles of buildings on the same site. It cost £2,400 (£ in 2015) and comprised a four-storey, eleven bay frontage long. The architect was the mayor, Marmaduke Pennell. The corporation offices moved here from Nottingham Guild Hall. A clock was presented for the Exchange by 1728 by the famous clock builder James Woolley of Codnor, and in return he was made a Burgess of Nottingham. The building was reconstructed between 1814 and 1815 at a cost of £14,000 To avoid confusion, in February 1846 the town council ordered that the town clocks be furnished with three hands, two indicating local time and the additional one the railway and post-office London time. A new clock was built in 1881 by G. & F. Cope and moved to St Helen's Church, Trowell in 1927. ==Nottingham Time Ball==

In 1876 a Greenwich time ball apparatus was fixed to the Smithy-row corner of the parapet of the Nottingham Exchange. It started operation on 11 September 1876. and was installed by the Corporation to indicate Greenwich Mean Time to assist with the regulation of public clocks. Operated by electrical control, the ball dropped from top to bottom of a short staff at 1pm each day. It was removed in 1886. Its use was probably discontinued because the installation had lost both its novelty and usefulness through the more general availability of Greenwich time, and the greater accuracy of public clocks. ==References==
