SMA Negeri 1 is nowadays one of the leading Senior High Schools in Semarang (Indonesia).
The school was built in Dutch colonial times as a Dutch High School. It is a beautiful example of Dutch colonial architecture: the building hardly changed its appearance since it was built in the 1930s. The first years of the school were turbulent: war, the Japanese occupation, and a short period when it was used as a Dutch military hospital. After the Dutch handed over power to Indonesia the school became an Indonesian High School.
