Operating since 1826, Lyon & Turnbull is one of the longest established fine art and antiques auction houses in the United Kingdom. The company maintains galleries in London and Glasgow with headquarters and main saleroom in Edinburgh. The neoclassical company HQ has been called the "most beautiful saleroom in Britain" and provides a stunning backdrop to over 20 specialist auctions per year. Lyon & Turnbull operates internationally, providing valuation and auction services worldwide. Expanding its reach into the international market, the company formed an alliance with America's oldest auctioneers, Freeman's of Philadelphia, in 2000.
