The Lycée de Garçons de Luxembourg.
Its name means 'boys' secondary school'; in Luxembourgish it is often just the 'Jongelycée'. It began in 1892 as the industrial and commercial school, split off from the Athénée, and in 1908 moved into its red-brick building here in Limpertsberg, designed by Gustave Serta. It took its present name in 1945; girls have been admitted since the 1960s.
