The Sacra di San Michele, sometimes known as Saint Michael's Abbey, is a religious complex on Mount Pirchiriano, situated on the south side of the Val di Susa overlooking the villages of Avigliana and Chiusa di San Michele, in the Piedmont region of northern Italy. The abbey, which for much of its history came under Benedictine rule, is now entrusted to the Rosminians. A special regional law acknowledges it as the "Symbolic monument of the Piedmont region". The book The Name of the Rose was inspired by this monumental abbey.
