The College is situated on a campus in Saint Saviour on the site of a former French Jesuit training school Notre Dame de Bon Secours that was established in Jersey in 1894 on the site known as Highlands. The school trained sailors for the French Navy but when the Jesuits were denied permission by anti-clerical laws to continue teaching, the school was moved to Jersey from Brest. The Jesuit period finished after World War I and the site was purchased by another French group The Brothers of Christian Instruction from Ploërmel in Brittany who set up a missionary school. During the second world war Jersey was occupied by the Germans and the site from 1941 was used to house 180 occupying forces. It returned to its previous use in 1945.
