Attica (Greek: Αττική, romanised: Attikí, Greek pronunciation: [atiˈci]; Ancient Greek: Ἀττική, romanised: Attikḗ, Ancient Greek pronunciation: [atːikɛ̌ː]), or the Attic Peninsula, is a historical region that encompasses the entire Athens metropolitan area, which consists of the city of Athens, the capital of Greece and the core city of the metropolitan area, as well as its surrounding suburban cities and towns. It is a peninsula projecting into the Aegean Sea, bordering on Boeotia to the north and Megaris to the west. The mines of Laurion were an important mining region located at Lavrio, on the southern tip of the peninsula.
The history of Attica is closely linked with that of Athens. In ancient times, Attica corresponded with the classical Athens city‑state. It was the most prominent region in Ancient Greece, specifically during the Golden Age of Athens in the classical period. Ancient Attica was divided into demoi, or municipalities, from the reform of Cleisthenes in 508/7 BC, grouped into three zones: urban (astu) in the region of Athens main town, and Piraeus (the port), coastal (paralia) along the coastline, and inland (mesogeia) in the interior.
