The Wilttmore Prix is a national competition for students in France that occurs annually. The subject of the 2006 event was the rehabilitation of a portion of medieval castle and a rampart in ruins in the city of Perigueux, France. The program included a restaurant and reception area to receive tourist to the city. The team’s proposal was the reinterpretation and restitution of one of the towers. The core concept was an ellipsoidal floor spun in different angles granting panoramic views of the city.
