Our Legacy


Years of ISB

The Oldest International School in Belgium

Established in 1951 as a not-for-profit organisation, ISB is the oldest international school in Belgium. Turning 70 is an important milestone in the history of our school. Looking back over the past seven decades and listening to the many students, parents, and employees that came before us, it is clear this is a school that leaves a lasting impression. Inspiring teachers, a beautiful campus, the Chateau, the joy of making life-long friends from every corner of the globe, and pathways towards a successful future beyond ISB.

There is no doubt that this is a school that leaves a mark on each one of us. It is also a school that challenges students to find their passion, pushes them to be better, and make their own mark in the world. 

ISB Chateau

The Château

An iconic building at the heart of our campus.
The Château des Fougères, or the Château Bischoffsheim, was built in 1854 as a country home for Baron Jonathan Raphael Bischoffsheim and his family. The Baron was a wealthy economist and financier from Frankfurt, in Belgium to help in the establishment of the new country and played an important role in shaping the economic policies of the new nation.
