To add to the other reviews, it is worth noting that on Sundays at midday the Mass is celebrated in the original Latin plainsong. Due to the exceptional accoustic qualities of the Abbey Church, this a remarkable event. Usually there are only three or four voices and the Priest, but they sound like ten times the number. Medeival singing at its finest underlines the atmosphere of this very ancient and sacred place. Entry is free after the tourists have left the site..
