The organization of the cloister consists of four squared-off piers at each corner and paired columns running along each of the arcades. The arcades are mounted atop a podium that extends along each side of the cloister. Each of the sides of the cloister has a grouping of four columns located at the center of the arcade. The six-foot-tall piers have medium-relief sculptural biblical scenes of the Post-Passion which are the Three Marys Discovering Jesus Christ is Gone, the Pentecost, the Doubting Thomas, and the Road to Emmaus. Originally, these religious scenes were painted in bright colors. These pier carvings are dated to the middle of the twelfth century and are the work of the sculptor of the lower story capitals. The carved panels are thought to be the work of the same craftsman who worked on the Abbey of St. Pierre de Moissac in France.
