Katholieke Studentenvereniging Sanctus Virgilius Delft

KSV (Katholieke Studenten Vereniging - Catholic Student Society) Sanctus Virgilius (also known as Virgiel) is the largest student fraternity/sorority in Delft. There are about 1600 students members (mostly students at TU Delft) who gather together on a daily or weekly basis at an old cloister named Alcuin, after the Irish builder/monk. It is a fraternity/sorority with old traditions and mores and it's named after Saint Virgil.

A wide variety of sports and cultural events are organized by members of Virgiel, e.g., soccer, field-hockey, climbing.

Virgiel was created in 1897 as the result of emancipation of the Catholic youth in the Netherlands. Catholicism had long been repressed by government policy, and Delft catholic students wanted to unite to discuss their faith and position in society. At the time, most members were also a member of the Delftsch Studenten Corps, the oldest student fraternity/sorority in town.

After the Second World War, Virgiel quickly grew, and on the wings of the sixties, quickly lost much of its religious objective. Virgiel is now a non-faith based fraternity/sorority, which is primarily aimed at having a very good time.
