The ground floor of the Clementine Tower was converted into a sacristy by the Maurist monks in the 17th century. What’s going on in this room and behind the closet doors? The European Heritage Days are an opportunity to discover the beauty and meaning of the woodwork that adorns the walls of the sacristy, objects and liturgical vestments of various eras. A brother of Saint John reveals these treasures to you on Sunday, September 18, from 2:30 pm to 5:30 pm – visit departs every half hour, to the right of the high altar of the abbey.
