Our heritage
Founded in 1903 by the Congregation of the Sisters of St.-Joseph, the Institut International de Lancy (IIL) was initially the Collège Marie-Thérèse.
The story.
As a Catholic boarding school for girls, we welcomed students from all over the world. 120 years later, we are one of the oldest private schools in Switzerland.
A non-profit association, we offer students an international education with a contemporary approach to academic achievement and personal development.
