The Abbey of San Caprasio in Aulla is a church, formerly part of a monastery, in Aulla, region of Tuscany, Italy. The monastery was established by the Benedictine order as a hostel on the pilgrimage route to Rome, and originally titled Santa Maria, in 1077 it was dedicated to San Caprasio, the patron of the town and a patron saint of pilgrims.
Documents cite the founding of the abbey within a fortification held by Adalberto I, Marquis of Tuscany. It later was linked to the Malaspina family and also contested by the Vescovi Conti of Luni. The abbey was powerful by the early 13th-century, owning various parishes and land in the area. The church was reconstructed in 1070 into the present layout, but has undergone many reconstructions over the centuries. It now serves as a museum and a hostel affiliated with the local parish.
