Co-cathedral of San Donato
The co-cathedral of San Donato was built from 1575 on the ruins of an earlier church that was elevated to the rank of cathedral of the diocese of Acerno in 444 by Pope Leo I. As a result of several seismic events, particularly that of 1980 and a subsequent fire, the structure underwent numerous structural modifications. With a renovation project in 1989, the church was completely restored and reopened for worship.
