01
A basilica in the harbor district
The church occupies part of an earlier Roman building complex near the ancient harbor. Its long history includes rebuilding and liturgical change, making it more than a single-date monument.

02
Why it is called the Double Church
Architectural phases created adjoining worship spaces that encouraged the later name Double Church. A guide can use the plan to explain how Christian buildings adapted older urban fabric.

03
The council connection
Tradition associates the basilica with the Council of 431. The location is essential for Christian history, but exact rooms and sequences should not be reconstructed beyond the evidence.
