The Metropole is famous for having hosted the first Solvay Conference in 1911. The International Solvay Institutes for Physics and Chemistry, located in Brussels, were founded by the Belgian industrialist Ernest Solvay in 1912, following the historic invitation-only 1911 Conseil Solvay, the first world physics conference. Just check out some of the names of the famous physicists in the photograph above which can be found in the lobby of the hotel - Planck, Lorentz, Madame Curie, Rutherford and Einstein!
It is also the birthplace of the Black Russian cocktail, which was created in 1949 by barman Gustave Tops for the United States ambassador to Luxembourg, Perle Mesta.
And of course nothing to beat relaxing for lunch and some nice Belgium beer in the Cafe' Metropole.
