The church’s plan remains the same as in the early 1000s, when churches were updated throughout Europe and cathedrals were introduced. The apse and façade of the church, which just over a century before, on 27 May 884, was founded by Adalberto I of Tuscany, were knocked down and rebuilt to lengthen the indoor space of the naves. The main altar was reconstructed using marble from the seventeenth-century altar erected in 1664 to host the relics of San Severo. The old tomb of San Caprasio can still be seen in the abbey’s apse. An English bomb weighing 500 pounds fell near the tomb in 1944. Having been unearthed in the archaeological digs of 2003, it was a miracle that it did not explode.
Every Friday, during Mass, the priest names all the pilgrims who have visited Aulla that week.
