Tiryns is a Mycenaean site in Argolis in the Peloponnese. It was a hill fort with occupation ranging back seven thousand years, from before the beginning of the Bronze Age. It reached its height between 1400 and 1200 BC, when it was one of the most important centers of the Mycenaean world, and in particular in Argolis. Its most notable features were its palace, its cyclopean tunnels and especially its walls, which gave the city its Homeric epithet of "mighty walled Tiryns".
