Lycée Emile Jacqmain, Rue Béliard, Brussels

Housed in the former Institute of Physiology,  a beautiful building, Lycée Emile Jacqmain is enviably situated on the edge of Leopold Park in Brussels' European district. Its pupils can be seen running around this hilly green space.  In 1927, the building hosted the fifth Solvay Conference, which brought together Albert Einstein, Niels Bohr, Marie Curie and more than a dozen other Nobel prize winners to discuss Quantum Theory.
