The Klenze-Gymnasium has a technological-scientific focus. This means that the subjects of chemistry and physics as well as computer science are emphasized in the intermediate and higher grades (8th-12th grade). In 1921, the school was founded as the Kreisoberrealschule III in the Klenzestraße and named after the street. At the moment, the Klenze-Gymnasium has about 900 students and 80 full-time teachers. It offers students the possibility to acquire the Baccalauréats and supplementary other tongue courses for students with Chinese, Italian, Spanish, Russian and new Greek as their mother tongue.
