Orte Cathedral

The Cathedral of Amelia has been qualified as a co-cathedral since 1986 when the Diocese of Amelia was unified with the Diocese of Terni and Narni. The old cathedral of Amelia dates back to the 9th century; it was seriously damaged by a fire or an earthquake in 1240 and rebuilt in Romanesque style. It was subsequently restored due to the severe damage suffered by the troops of Frederick II in the 13th century. A fire almost completely destroyed the building in 1629 and it was rebuilt in Baroque style. The façade was completed in the 19th century.

The Cathedral of Civita Castellana was built from around 1185, on top of an earlier sacred building, and was completed with the construction of the portico in 1210. After falling into disrepair over the centuries, the interior of the church was completely renovated in the 18th century in the Baroque style: the transformation of the three-nave church into a single-nave church with interconnected side chapels dates from this period.

The church of Santa Maria Nuova is a Romanesque church dating from the 11th century. The present church must have been built on the site of a pre-existing sacred building, perhaps dating from the 6th century, dedicated to the Virgin, or even a pagan temple dedicated to Jupiter. Restoration work carried out between 1907 and 1914 restored the church to its original style, after additions made between the 17th and 19th centuries.
