I came here with my parents in the last week of the summer vacation and I really felt very educated. The German Prison Site Museum is located at No. 23 Changzhou Road, Qingdao City. It was built in 1900. It is the only castle-style building in the modern history of Chinese prisons. The museum of the former German prison site, formerly known as the "European Prison", is the earliest colonial prison in China. The former site covers an area of 11.8 mu and a construction area of 8297.5 square meters.
