Loëns' grange à dîme (tithe barn) now houses the International Stained-Glass Centre, an art form of which Chartres is indisputably the capital. This "cultural and technical centre for glass, stained-glass and light" highlights contemporary and traditional creation in the field of decorative glass. In the magnificent triple-naved Gothic hall (12C), exhibitions and educational workshops are held. Interesting tour about the cathedral's stained-glass windows.
