Neolithic The area has been inhabited since
prehistory. A small
neolithic settlement thrived.
Early Helladic In the middle of the 3rd millennium BC, it was a flourishing early pre-Hellenic settlement located about southeast of
Mycenae, on a hill long, wide, and no more than high. From this period, an imposing circular structure survived under the yard of a Mycenaean palace. It was in diameter. It appears to be a fortified
area of refuge for the city's inhabitants in time of war, and/or a residence of a king. Its base was powerful, and was constructed from two concentric stone walls, among which there were others cross-cutting, so that the thickness reached . The superstructure was clay and the roof was made from fire-baked tiles.
Middle Helladic The first Greek inhabitants—the creators of the Middle
Helladic civilization and the
Mycenaean civilization after that—settled Tiryns at the beginning of the Middle Helladic period (2000–1600 BC).
Late Helladic In the Late Helladic, the city underwent its greatest growth, also known as the Mycenaean period. The Acropolis was constructed in three phases, the first at the end of the Late Helladic II period (1500–1400 BC), the second in Late Helladic III (1400–1300 BC), and the third at the end of the Late Helladic III B (1300–1200 BC). The surviving ruins of the Mycenaean citadel date to the end of the third period. The city proper surrounded the acropolis on the plain below. The
disaster that struck the Mycenaean centers at the end of the
Bronze Age affected Tiryns, but it is certain that the area of the palace was inhabited continuously into the early
Archaic period, until the middle of the 8th century BC (a little later a temple was built in the ruins of the palace). In the post-palatial LH IIIC period (), an extensive deposit of precious items, including gold and silver objects and a fifteenth-century BC Minoan
signet ring, was made in a
cauldron in Tiryns's lower town, within the foundations of a Mycenaean house.
Classical period At the beginning of the
Classical period Tiryns, like Mycenae, became a relatively insignificant city. When
Cleomenes I of
Sparta defeated the
Argives, their slaves occupied Tiryns for many years, according to
Herodotus. Herodotus also mentions that Tiryns took part in the
Battle of Plataea in 480 BC with 400
hoplites. Even in decline, Mycenae and Tiryns were disturbing to the Argives, who in their political
propaganda wanted to monopolize the glory of legendary (and mythical) ancestors. In 468 BC, Argos completely destroyed both Mycenae and Tiryns, and—according to Pausanias—transferred the residents to Argos, to increase the population of the city. However,
Strabo says that many Tirynthians moved to found the city of Halieis, modern
Porto Heli. Despite its importance, little value was given to Tiryns and its mythical rulers and traditions by
epics and drama. Pausanias dedicated a short piece (2.25.8) to Tiryns, and newer travelers, traveling to Greece in search of places where the heroes of the ancient texts lived, did not understand the significance of the city. ==Excavations==
