When the school was founded it was located on the premises of a former furniture shop in the Limpertsberg quarter of Luxembourg city. It initially had 70 students. The school later moved to Villa Lentz in Hollerich. In 1956 construction began on a new building, located on Boulevard de la Foire, just outside the city centre. The building was opened in 1957, on 11 December. This building today houses the language teaching centre of Luxembourg. The first students graduated in 1959; the graduating class was 23.
