In addition to the ruins of a basilica with an atrium (6C) and the finds excavated at the prehistoric site of Dikili Tash on display in the museum, there is a great theatre dating back to the 4C BC. It was refurbished by the Romans in the 2C, then remodelled in the 3C when the stage was converted into an arena for gladiatorial and animal fights. The low-reliefs on the entrance pillar show Mars and Victory and a splendid bucranium (sculptered ox-skull).

The museum's collections are well presented in a modern building. Room 1 is devoted to the excavations at Neapolis. Note the colossal Ionic capitals from the sanctuary of Parthenos (6C-5C BC) excavated near the Imarét, a huge building built in the Muslim style. Room 2 contains items from the necropolis at Amphipolis: carved stele, glass and gold Hellenistic jewellery (300-100 BC).

Neapolis Gate, the entrance to Philippi (Fílipi) from Kavála, was part of the Byzantine walls, which still exist in places and were reinforced with towers. The section running north climbs up to the Greek acropolis where three towers were built in the Middle Ages. The area between the walls and the forum is still being excavated. The French School in Athens has discovered traces of a large palaeo-Christian basilica built exceptionally on an octagonal plan, a baptistery and a bishop's palace.
