The Pieria regional unit is bordered by Imathia to the north, Kozani to the west, and to the south and west by the region of Thessaly's regional unit Larissa. The Pierian Mountains lie to the west; the Thermaic Gulf lies to the east. It also has a valley by the GR-13. Most of the population live within the Olympian Riviera. The lowest point is the Thermiac Gulf and the highest point is Mount Olympus. It combines extensive plains, high mountains and sandy beaches. The region's beauty gives it a great potential for further tourist development.
Climate
Its climate is mainly of Mediterranean type with hot summers and cool winters. Severe winter weather is common in the central and western parts of Pieria, especially in the Pierian Mountains and on Mount Olympus. On June 8, 2007, a low pressure weather system from Southern and Central Europe resulted in heavy rainfall that ravaged the prefecture and caused great damage in fruit and vegetable production. The worst hit area was Korinos.
Administration
The regional unit Pieria is divided into 3 municipalities. These are :
Pydna-Kolindros
Katerini
Dion-Olympos
Prefecture
As a part of the 2011 Kallikratis government reform, the regional unit Pieria was created out of the former prefecture Pieria. The prefecture had the same territory as the present regional unit. At the same time, the municipalities were reorganized, according to the table below.
The region, known as Pieria or Pieris in Antiquity, took its name from the Pieres, a Thracian tribe that was expelled by the Macedonians in the 8th century BC from their original seats, and driven to the North beyond the Strymon river and Mount Pangaeus, where they formed a new settlement in Edonis. The name Pieria has been connected to Homeric πῖαρ "fat", πίειραν ἄρουραν "fertile land" in a metaphorical sense. At some time before the archaic period Pieria was incorporated in the Kingdom of Macedon when it became the second province of the ancient kingdom, following its fate through the rule of the Antipatrid dynasty and the Antigonid dynasty. It became part of the Roman Republic after the Fourth Macedonian War, and remained part of the Roman Empire and its successor, the Byzantine Empire. It was later invaded and became a part of the Ottoman Empire. During the Greek War of Independence in 1821, Pieria took up arms along with the rest of Greece, but their struggle failed and Pieria did not join the rest of Greece until the Balkan Wars in 1913. Until 1947, Pieria was part of the Thessaloniki Prefecture, as a province. Pieria saw an economic boom in agriculture and business. During the Greco-Turkish War, it saw an influx of refugees from Asia Minor, now a part of Turkey, and several places were named after their former homelands including Nea Trapezounta from Trebizond and Nea Efesos from Ephesus. The village of Elafos in the municipal unit Elafina, formerly a community in the Imathia prefecture, was united with Pieria in 1974.
