In 1885, Bechstein opened a branch in London, that eventually grew to become the largest showroom and dealership in Europe. In 1889 he moved to 40 Wigmore Street, taking over the property of H.J. Cave & Sons By 1890, showrooms opened in Paris, Vienna, and Saint Petersburg. On 31 May 1901, Bechstein Hall, built at a cost of £100,000, opened next to the company's London showroom at 36-40 Wigmore Street. Between 1901 and 1914, C. Bechstein was the largest piano dealership in London. At that time, Bechstein was patronized by the tsars of Russia, the royal families of Spain, Belgium, the Netherlands, Italy, Sweden, Norway, Austria and Denmark, and other royalty and aristocracy. The list of royal clients of Bechstein may be found on the soundboard of vintage Bechstein pianos made before the Second World War. The list is part of the original Bechstein trademark logo; it can be seen under the strings in the centre of a piano's soundboard.
