It was founded in 1818 by Caroline Wroblewsky as a school for young girls, and since 1972 it has been located in Husum, Denmark.

In 1818, the year of her father's death, Marie Albertine Caroline Wroblewsky sent in an application for an “institution of general education for a limited amount of young girls.” She was rejected as there were already too many schools in the Trinitatis parish.

In 1824 the school was expanded to include older girls and Lieutenant Larsen was hired to teach French.

The subjects taught were religion, Danish, German, French, history, geography, nature study, arithmetic, writing, drawing, singing and needlework.

On September 11, 1858, Løbner took an exam to become a 3rd-degree institution manager, giving her the right to expand the school and teach girls up to the age of 16.

Because of the continued increase in the student body, Karen Kjær moved the school to an independent building in the Gartnergade neighborhood in 1897.

Thejll was concerned about the lack of space and other problems with the school's layout and sought a solution in 1932.

It was also during Thejll's tenure that Nørre high school students started going on seven-day study trips, usually within Denmark, sometimes going into Sweden.

The school was also aging; the physics and chemistry labs were at low standards, and there was no large assembly hall or bicycle storage area.

Thus, under Hasselriis, Nørre Gymnasium lost its popularity and began to lose students.
