imperial approach and instead, with a firm grip, bring the empire closer than ever before." Smith's ideas thus played an important part in subsequent debates over the British Empire. Portraits, monuments, and banknotes Smith has been commemorated in the UK on banknotes printed by two different banks; his portrait has appeared since 1981 on the £50 notes issued by the Clydesdale Bank in Scotland, and in March 2007 Smith's image also appeared on the new series of £20 notes issued by the Bank of England, making him the first Scotsman to feature on an English banknote. A large-scale memorial of Smith by Alexander Stoddart was unveiled on 4 July 2008 in Edinburgh. It is a -tall bronze sculpture and it stands above the Royal Mile outside St Giles' Cathedral in Parliament Square, near the Mercat cross. 20th-century sculptor Jim Sanborn (best known for the Kryptos sculpture at the United States Central Intelligence Agency) has created multiple pieces which feature Smith's work. At Central Connecticut State University is Circulating Capital, a tall cylinder which features an extract from The Wealth of Nations on the lower half, and on the upper half, some of the same text, but represented in binary code. At the University of North Carolina at Charlotte, outside the Belk College of Business Administration, is Adam Smith's Spinning Top. Another Smith sculpture is at Cleveland State University. He also appears as the narrator in the 2013 play The Low Road, centred on a proponent on laissez-faire economics in the late 18th century, but dealing obliquely with the financial crisis of 2007–2008 and the recession which followed; in the premiere production, he was portrayed by Bill Paterson. A bust of Smith is in the Hall of Heroes of the National Wallace Monument in Stirling. Residence Adam Smith resided at Panmure House from 1778 to 1790. This residence has now been purchased by the Edinburgh Business School at Heriot-Watt University and fundraising has begun to restore it. Part of the Northern end of the original building appears to have been demolished in the 19th century to make way for an iron foundry. As a symbol of free-market economics Smith has been celebrated by advocates of free-market policies as the founder of free-market economics, a view reflected in the naming of bodies such as the Adam Smith Institute in London, multiple entities known as the "Adam Smith Society", including an historical Italian
