The villa on the edge of the Mathildenhoehe was built in 1908 for Paul Ostermann, the director of the collection of the grand duchy, by Alfred Messel, the architect of the state museum. The classsical style of the villa bears no relation to the Art Nouveau of the neighbouring Artists‘ Colony. Today Ostermann House, also known as Alfred-Messel-House, is the home of "Hessen Design“.
