A narrow, sunny space with low stone walls and plants which like dry soils extends the Procurer’s garden to the east. This small space is known as the “Memory Garden” for it holds stones from the chapel and the vaulted ceiling that once stood above the choir, and other vestiges. The vast view over the ramparts of the Fort Saint André, and the bright stony sunlight here gives a feeling of the Mount of Olives. The presence of this small garden right next to the ruined nave, near the tomb of Pope Innocent VI, determined the choice of emblematic plants such as olive trees, coronilla and other yellow and white-flowering plants.
In 2014, two heritage pear trees - Marquise and Crassane - from among the thirteen varieties descended from the first Carthusian monks, were planted in this Memory Garden.
