The Basilica of Aquileia
The church today is essentially the result of the architectural works promoted by bishop (patriarch) Poppo (1019- 1042), who consecrated it in 1031. However, its origins go back to the second decade of the 4th century. By the end of the same century, under the rule of bishop Chromatius, the edifice had grown into the current dimensions, except for the transept and apse with the underground crypt.
