The school was founded in 1851 by Natalie Zahle as a girls' school and within nine years was the largest in Denmark. It has stood on Nørre Voldgade since 1877. Today it has two private primary schools (grades 0-9), each with its own teaching staff, a private upper secondary school (STX) next to Nørreport Station, and a music and art school for children and young people.
The school also offers after-school care (SFO).
