Isabelle Gatti de Gamond Royal Atheneum  The Isabelle Gatti de Gamond Royal Atheneum (French: "Athénée royal Isabelle Gatti de Gamond") is a French-speaking K-12 school located in Brussels, Belgium. When founded in 1864 by Isabelle Gatti de Gamond, the school was the first non-confessional school for girls in Belgium. Established on October 3, 1864, under the name "Cours supérieur d'éducation pour jeunes filles", the school is the oldest state middle and high school for girls in Belgium. The school extended its curriculum throughout the second half of the 19th century with the creation of a kindergarten (1879), a department of pedagogy providing educational training to future female schoolteachers (1880) and a university preparatory department (1894). It was named "Lycée royal Gatti de Gamond" in 1948 and adopted its current name with the implementation of mixed-sex education in 1976. Since the closure of the Athénée royal de Bruxelles () in 2002, the school has been the only state atheneum in the "Communauté française" network located within the limits of the Brussels historical city center.
