Opened originally in 1971 as a two-storey complex dedicated solely to the sciences, with a bottom floor reserved for the arts – an art room and a media room for debates. In 1979, a third storey was added with two new laboratories. Today, the two top storeys are dedicated to science laboratories, with the bottom levels incorporating a technical drawings room, classrooms and a catering centre. The swimming pool is located near the Mendel complex. The complex is named for Gregor Mendel.
