Patriarchal Basilica of Aquileia
This spectacular basilica comes from the 4th century and was built on the initiative of Bishop Theodore. This first church consisted of two parallel chambers (and one that connected), as well as other rooms and the baptistery, which is still preserved. Subsequently, this first building suffered various modifications over the centuries, such as the plant changing by a cross, or the construction of a crypt under the chancel. It was the seat of the Patriarchate of Aquileia, which played an important role in the history of the area. The first thing a visitor will see when entering the basilica are the mosaics that cover the entire floor of the nave and aisles, and the magnificent frescoes.
