At the main entrance in the commercial harbor of Constanța one can notice a small area where rests of an ancient Christian basilica are preserved. Only the apse is still visible today, as well as rests of an earlier rectangular complex, overlapped by this basilica. This part of the city, situated in front of the ancient harbor, was probably dedicated to commercial structures in the Hellenistic and Early Roman times. The change in the functionality of this area occurred in the 5th century AD, when a Christian structure had to be raised in this part of the city, over the 4th century building. Christian symbols and objects belonging to the Christian practice in Tomis or Scythia province can be admired in the exhibits of the Museum for National History Constanța.
