The southern wing carries the best front on the building: its doors and its columns crowned with Corinthian capitals, and before them a large narthex running the width of three aisles, the middle one widest. Each aisle is five arches on six columns.
The detail that proves what this church was for is behind that front. There are two doorways into the central hall — one to go in by and one to come out by. The building has a one-way system, cut in stone in the fifth century, because the numbers arriving made it necessary.
Among the blocks recovered from the rubble of this basilica is one carved with the Chi-Rho — the first two letters of Christos in Greek — set between Alpha and Omega, the first and last letters of the alphabet.
