Prehistoric Pydna

Even from Mycenaean times (1400 BC) settlements were found in the hills north of the excavation site. From 1000 to about 600 BC the area was inhabited by Thracians. However, the settlement is not completely preserved because the eastern part has slipped into the sea. Thus, only the western half of the settlement is preserved, which, however, has not yet been excavated.

Classical Pydna

Pydna was first mentioned by the Greek historian Thucydides and gained importance during the Peloponnesian War.^[1] The Athenians besieged Pydna in 432 BC.^[2] King Archelaus I of Macedonia besieged the city by 410 BC from the land side, while the Athenian fleet took over the siege from the sea. After the city was taken, Archelaus moved the city 20 stadia far into the inland, to the present place of Kitros.^[3] After Archelaus's death, the inhabitants of Pydna moved back to their old seaside site. Pydna was conquered by the Athenians, but fell in 357 or 356 BC to King Philip II, the father of Alexander the Great. Philip's wife, the mother of Alexander, Olympias, was killed there after a siege by Cassander 317 BC.^[4] On 22 June 168 BC, the Battle of Pydna between the Roman commander Aemilius Paullus and the last Macedonian king Perseus took place. On this day the Macedonian rule ended, and in the course of the Roman victory, Macedonia became a Roman colony.

Parts of the city wall, built in the 5th century BC, are located 500 m north of the ancient site. The exact course of the city wall is unknown. In excavation work, only parts have been discovered so far. The wall was not made of stone but of clay. It was destroyed after the city was taken by Philip II.

Pydna issued its own coins for the first time in the late 6th century BC. Further coins were found dating from between 389 and 379 BC.^[5]

Ancient Pydna was already a part of the Macedonian kingdom under Alexander I (Thucydides I.137.1). It was unsuccessfully besieged by the Athenians in 432 BC and again, after seceding from the Macedonian kingdom, in 410 BC by Archelaus I who successfully captured the city and transferred its population further inland, possibly at the site of modern Kitros; however, the old site was re-populated in the early 4th century. The Athenians, under Timotheus, seized Pydna in 364-363 BC, only to have it retaken in 357 BC by Philip II of Macedon. Pydna would remain part of the kingdom of Macedonia until its Roman conquest. In 317 BC, Alexander III's mother, Olympias took refuge there to escape from Cassander's wrath, incurred by Olympias' scheming against Phillip III and his wife. Cassander besieged the city and managed to capture it during the spring of 316 BC.

Roman Pydna

The Battle of Pydna (June 22, 168 BC), in which the Roman general Lucius Aemilius Paullus (subsequently given the nickname of "Macedonicus") defeated King Perseus, ended the reign of the Antigonid dynasty over Macedon.

Christian Pydna

The Christianization of Pydna began in the fourth century. At this time the first basilica was built. At the beginning of the 6th century a second basilica was built. Both basilicas were dedicated to the patron of the city, St. Alexander. The second basilica was burnt down after an attack by the Bulgarians. At the end of the 10th century a much larger basilica was built in its place. It measured 23.20 m by 16.60 m. It was decorated with frescoes and the floor was laid out with mosaic. During the Franconian period, the basilica was expanded into a fortress. A well was drilled and supplies were laid. Inside the basilica is a 22 meter deep well with a stone fountain. Next to the well there was a cistern. A subterranean corridor was dug, which was to allow the crew of the castle to escape outside.

In the apse, facing the sea, there was a Fryktoria, to exchange light signals with the opposite Chalkidiki peninsula.^[6][7] In this way, light signals were transmitted to larger distances by means of torches, and messages could be transmitted within a short time over hundreds of kilometers.

Spolias (remains and fragments of columns and other masonry work) were incorporated into the surrounding wall. The wall was built in two phases. In the 6th century, during the time of Justinian, the first construction phase took place. In the 10th century the wall was reinforced and some of the gates were walled up. The wall is about 1.40 m thick and was reinforced by rectangular towers. Some of the remains of the complex date from the 16th century, the time of the occupation of Greece by the Ottomans.

West of the road, which formerly connected Pydna with Dion, are remains of the city walls and a city gate to be seen. The current course of the road is largely identical to that of the ancient road.

Late in the first millennium of the Christian era Pydna became a bishopric under the name Kitros or Citrus. It is included in the Notitia Episcopatuum of Leo VI the Wise (866–912). Its bishop Germanus participated in the Photian Council of Constantinople (879). In the aftermath of the Fourth Crusade Citrus became a Latin Church diocese, as witnessed by a letter of Pope Innocent III in 1208, which does not give the name of the bishop of the see.^{[8][9][10][11]} It is now listed by the Catholic Church as a titular see.^[12]

Medieval Pydna

Between the 6th and 7th century AD, Pydna was named Kitros, and was the most important town of Pieria until the 14th century. In the 11th and 12th centuries Kitros was the seat of a Katepanikion.

In 1204 Kitros, after a siege, was taken by the Franks. They turned the bishop's church into a castle and built a tower in which their commander-in-chief resided.

In the 14th century the inhabitants left the village and settled in today's Kitros, in the inland of the country.
