Soil shipped from Calvary during the Crusades is said to lie within the white walls of this hauntingly beautiful, final resting place for many prominent Pisans, arranged around a garden in a cloistered quadrangle. During WWII, Allied artillery destroyed many of the cloisters' frescos, but a couple were salvaged and are now displayed in the Sala Affreschi (Frescoes Room).
Most notable is the Triumph of Death (133–41), a remarkable illustration of Hell attributed to 14th-century painter Buonamico Buffalmacco. Fortunately, the mirrors apparently once stuck next to the graphic, no-holds-barred images of the damned being roasted alive on spits have since been removed – meaning a marginally less uncomfortable visit for visitors who would have once seen their own faces peering out of the cruel wall painting. Buffalmacco's Last Judgement & Hell (1336–41), in the same room, is equally brutal.
