Co-Cathedral of St. Secundian

The Co-Cathedral of St. Secondian is an Early Christian church in Chiusi featuring an elevated central nave and traditional architectural elements of that period. The interior displays the structural characteristics typical of churches from this era.

Originally the cathedral of Chiusi, it was redesignated in 1986 through papal reorganization when it became part of the Diocese of Montepulciano-Chiusi-Pienza. This administrative change altered its formal role within the local church structure.

The cathedral is dedicated to St. Secondian, an early Christian martyr whose veneration shaped local religious life for centuries. His memory remains central to how people in Chiusi understand their spiritual heritage.

The church is situated on Piazza Duomo in central Chiusi and is easily accessible on foot. Visitors should respect regular opening hours and wear appropriate clothing when entering.

Two dignitaries jointly oversee the cathedral chapter, combining spiritual leadership with parish administration. This shared responsibility is uncommon and reflects special church regulations established for this diocese.
