The Region of Western Greece stretches from the northwest part of the Peloponnese to the western tip of the Greek mainland. It is one of the 13 Regions of Greece, is separated in 3 administrative districts, the Prefectures of Aitoloakarnania, Achaia, Ilia and covers an area of 11.350 square kilometres (8,6% of the total area of Greece).

For the most part the terrain is mountainous (45,3%) or hilly (25,6%), while only 29,1% consists of plains. All three prefectures have extensive coastal areas along the Ionian Sea and the Gulfs of Ambracia, Patras and Corinth.

According to the 2001 census, the population of the Region of Western Greece is 741,282. This makes it the fourth most populated Region of Greece, with 7% of the country’s total population. 

Today the Region of Western Greece is a modern communications and transport hub that connects Greece to the rest of Europe. The busy port of Patras is not only the Region’s capital but also the country’s main gateway to Western Europe.
