Peloponnese (region)

The Peloponnese Region (Περιφέρεια Πελοποννήσου, ) is a region in southern Greece. It borders Western Greece to the north and Attica to the north-east. The region has an area of about 15490 km2. It covers most of the Peloponnese peninsula, except for the northwestern subregions of Achaea and Elis which belong to Western Greece and a small portion of the Argolid peninsula that is part of Attica.

Administration
The Peloponnese Region was established in the 1987 administrative reform. With the 2011 Kallikratis plan, its powers and authority were redefined and extended. Along with the Western Greece and Ionian Islands regions, it is supervised by the Decentralized Administration of Peloponnese, Western Greece and the Ionian Islands based at Patras.

The region is based at Tripoli and is divided into five regional units (pre-Kallikratis prefectures), which are further subdivided into 26 municipalities. The largest city of the region is Kalamata.
