ISB has three campuses, conveniently located just south of Basel city in Reinach, Fiechten, and Aesch.

In order to most successfully accomplish our school’s student-centred mission, the International School of Basel (ISB) spans three individual campuses. This arrangement enables us to provide three unique and age-appropriate learning environments, which in turn increases each student’s sense of security and belonging in our school. Moreover, it allows us to provide the actual safety and security measures required of any world-class international school in this day and age.

From Aesch’s early learners, to Fiechten’s middle years’ students, to Reinach’s young adults, we hope you will appreciate the well-designed progression in architecture, resources, and student-driven organization. We invite you to visit us soon!
