The Founder Duels were a secret inter-House duelling championship during the 1990s. Champions were selected to represent each house (Hufflepuff, Ravenclaw and Slytherin Wizard Duelling Champions). The duelling areas (an open turrets area, a fenced yard and a dungeon) could be found past a secret passage in the statue of the Architect of Hogwarts, accessible behind the portraits of a Hufflepuff lady, a Ravenclaw lady and a Slytherin nobleman.
