History of Pieria (regional unit) in the context of "Leibethra"

The Platamon Castle (Greek: Κάστρο του Πλαταμώνα), an important part of the history of Pieria, is a Crusader castle (built between 1204 and 1222) in Macedonia, Greece and is located southeast of Mount Olympus, in a strategic position which controls the exit of the Tempe valley, through which passes the main road connecting Macedonia with Thessaly and southern Greece. The tower (donjon), which overlooks the highway, is an imposing medieval fortress.

Important discoveries are the board of Hellenistic wall, that confirm the suggestion that on this position was the ancient Greek city Herakleion and the gate in the wall of the donjon. The core of the city Herakleion remains to be found, but it is posited that it is located on the northwest side of the castle's hill due to shells and coins found during recent excavations.

The Archaeological Park of Dion is the most important archaeological site at Mount Olympus in Greece, located in Dion (Greek: Δίον). In the area comprised by the Archaeological Park of Dion, sanctuaries were found from the Hellenistic and Roman periods. The park displays the importance of ancient Dion in the history of Pieria.

Pydna (Greek: Πύδνα) was an ancient Greek city in what is now the regional unit of Pieria, Central Macedonia, Greece. It is an important place in the history of Pieria and a major archaeological site located directly at the Aegean Sea, 16 km northeast of Katerini, 28 km north-east of Dion and 2.5 km from the village of Makrygialos. Nearby are two Macedonian tombs, discovered by the French archaeologist Heuzey during his Greek travels in the mid-19th century. Furthermore, the fortress-like bishop's seat Louloudies is located a few kilometers south of Pydna.

Leibethra or Libethra, in the modern pronunciation Leivithra (Greek: Λείβηθρα or Λίβηθρα), was an ancient Macedonian city at the foot of Mount Olympus, near the present settlement of Skotina. Archaeologists have discovered tombs there from the late Bronze Age (13th–12th century BC) containing rich burial objects. Leivithra played a remarkable role in the history of Pieria.

Louloudies (Greek: Λουλουδιές, [lu.lu.ˈðjes]) is an archaeological site in Pieria, northern Greece. It comprises a fortified bishop's seat from the Byzantine era, discovered during the construction of the railway line between Athens and Thessaloniki.

Louloudies is an important place of the early Christian history of Pieria.
