Nations and takes place at the GSA campus. It is designed for secondary school students and is intended to provide an occasion for the participants to discuss world issues. The conference gives them the opportunity to experience the work of the United Nations and to get to know the world of diplomacy. The delegates at the DSAMUN conference are asked to prepare drafts resolutions and policy statements on various issues (from the view of the country they represent) and learn to negotiate and debate in a formal way. Foreign students, who attend DSAMUN, have the opportunity to visit Plaka, the National Museum, the Acropolis and other places of interest in Athens. In addition, excursions to Epidaurus and Nafplion are organized. Dörpfeldianer Ball The Dörpfeldianer Ball for graduates takes place every two years at the Hotel Athenaeum Intercontinental. It draws together people from the fields of politics, diplomacy, business, journalism and the academic world. The highlight of the Dörpfeldianer Ball is the debut of the 'débutantes' (female graduating students of the school) in dances like waltz and polka. The tradition of the débutantes signifies the step into adulthood and social life. The dress code is formal. Drama Groups The German School of Athens has at various times had between one and three drama groups staging plays in both the Greek, German and English language. These are classified as extracurricular activities or AGs (short for the German term "Arbeitsgemeinschaften"). While the English- and German language drama groups have been led by different members of the teaching staff over the years, and were periodically not offered as AGs, the Greek Drama Group had been consistently led by Mr. Stelios Papapetrou who in 2010 passed his experience and knowledge to Mrs. Elena Karakouli, the group's current leader. In the year 2010 the group celebrated its 30th anniversary, a time during which it had been awarded many times by theatre organisations in Greece. Most of the props and stage sets for the various plays are provided by the school's art department, particularly the Art and Stage Sets Group. Additionally, 20 graduates of the DSA/ΓΣΑ and former members of the school theatrical group are professional actors, such as Alexandra Pavlidou and Thalia Matika. Greek Music Group The German School of Athens also has a Greek music group. The Group has been led for 15 years or more by philologists and musicians Dr. Giannis Mangidis and Dr.
