No, not the band. Twenty-four members of the ruling family of León are entombed in the Panteon in the Basilica of San Isidoro in León. The iconography on the ceiling of the royal crypt dates to the 10th century. The Pantokrator and the Last Supper were clearly recognizable to Orthodox eyes. The library and treasury of the monastery attached to the Basilica have been looted several times over the centuries, but they still have a Bible dated to around the year 960 AD and a communion chalice also from the 10th century.
In Canada, we consider a church to be an historic building if it's been around for a hundred years or so.
