We also know that the exploitation of the silver mines of Lavreotiki, at the site of ancient Thoricos dates back to this period of time; thanks to that, Athens had obtained its prosperity and achieved to flourish. In Athens, the palace of the king and the mansions of his officers were situated on the Acropolis, fortified as early as in the 14th century b.C. As in all Mycenaean sites, these walls were made of huge stones; for this reason they were thought to have been constructed by the Cyclops and called “cyclopean”; a part of this early fortification is still visible at the base of the walls of Acropolis surviving today. A Mycenaean cemetery has been found at the site of Ancient Agora and a rich tomb at the hillside of Acropolis. Similar ones are also scattered in Attica, as at Menidi, at Marathon, at Spata, at Thoricos and at Keratea.
It is worth mentioning that in this period of time the port of Athens was at Phaleron; also, according Homer, the Athenians took part to the Trojan War, under their king Menestheus.
By mid-14th century b.C. Theseus, the mythic king and hero of Athens had united all the settlements of Attica (except Megara and Eleusis) under his power and made Athens the seat of his state. Panathinaea, the greatest and most famous feast of ancient Athens was established to honor this important fact.
By the end of the 12th century, the Dorians invaded Attica, but did not achieve to take possession of it; they could conquer only Megara and settled there. This fact is connected with the abolishment of kingship in Athens; from this period monarchy is substituted by an oligarchic regime, which would last throughout the next period.
