Cella septichora is a collection of Roman-era excavations, consisting of tombs and other buildings. The ruins are located underground, making this an excellent location on a warm or rainy day. You can walk around the corridors and paths above and between the ruins. The tombs in particular are full of well-preserved frescoes and are very easy to view. When purchasing your entrance ticket, you also receive the entrance to the Early Christian Mausuleum, a very well-preserved tomb diagonally opposite the entrance to Cella Septichora..
