The remains of an early Christian basilica and cemetery just outside the city walls were partially uncovered in the Sixties. The two mosaic floors, one above the other, belonging to two periods of use of the religious building, refer respectively to the end of the 4th-early 5th century and to the 6th century. In the presbytery, positioned at a higher level than the hall, it is possible to observe a niche for reliquaries, which was probably located under the altar slab. The Basilica testifies to the importance and wealth of the Triestine Church: in the inscriptions inserted in the mosaic floor the words Sancte Ecclesia Tergestina appear for the first time, and the names of various donors are mentioned, some of Greek and Oriental origin, reflecting the cosmopolitan character of the city and its relations with those regions at the time.
