Remains of Ancient Greek Naval Base Discovered Near Athens.

A TEAM working off the coast of Athens has uncovered the remains of an ancient naval base, estimated to be about 2,500 years old.

Some 2,500 years ago, a severely outnumbered Greek naval fleet managed to halt a force of invading Persians in a decisive clash fought in the narrow strait between the Greek mainland and the island of Salamis. Essential to the Greek victory were some 200 three-banked warships, known as triremes. When not in battle, these all-important vessels were housed in a massive naval facility in Athens’ seaport, Piraeus. As part of a recent excavation of Piraeus Harbor, a team of Danish and Greek marine archaeologists discovered the remains of an ancient naval base estimated to date to between 520 and 480 B.C., the year the Battle of Salamis took place. With six sheds, each designed to hold hundreds of vessels, the complex would have been one of the largest structures in the ancient world.

In 2001, a team of marine archaeologists led by Bjørn Lovén of the University of Copenhagen launched the Zea Harbor Project, a major land and underwater investigation in search of the ancient Athenian naval bases of Zea and Mounichia. They got a huge break in 2010, when a local fisherman guided them to a site on the northern side of Mounichia, in an area now used for fishing and yachting.

After searching through a tangle of anchors, chains and modern-day debris, the archaeologists eventually uncovered six ship-sheds, the structures that housed and protected the ancient Greek war vessels known as triremes. As Lovén announced recently in a press release: “Based on pottery and carbon-14 dating from a worked piece of wood found inside the foundations of a colonnade, we dated the ship-sheds to around 520-480 BCE, or shortly thereafter.”

The team’s discovery of the remains of the ancient naval base built at Piraeus, Athens’ harbor city, represent a window into a pivotal moment in Greek history: the triumph of an alliance of Greek city-states over an invading Persian force in the Battle of Salamis, in 480 B.C. A few years before the battle, the Athenian statesman Themistocles had predicted a future attack by Xerxes, the powerful emperor of Persia. He determined that a strong navy would be Greece’s best defense against such an invasion, and pushed for the construction of a fleet of triremes, three-banked war vessels, to be based in Piraeus. In order to protect this vital naval defense system, the ancient Athenians built a massive facility at Piraeus that would rank with the Acropolis and the Parthenon among the most formidable structures in the ancient world.

Triremes would prove to be the key to building Greece’s naval power, both before and after the Battle of Salamis. The vessels were exceedingly vulnerable to damage, not just when at sea or in battle, but also while moored in the harbor. Excessive exposure to the punishing summer sun would dry out and shrink the timbers of the ships’ hulls, creating leaks, while exposure to rain would cause swelling and fungal decay in the wood. Ship-sheds, like those found by Lovén and his colleagues, were used to protect the vessels from these risks, as well as from damage by the wood-eating mollusks known as shipworms, or woodworms.

By the late fourth century B.C., the complex of naval bases built at Piraeus could house more than 350 triremes. The ship-sheds, long parallel buildings measuring some 6 ½ meters wide and up to 80 meters long, had ramps along each side sloping up from the water. According to “The Wooden Wall,” a short film produced by Lovén about the Battle of Salamis and the Athenian naval bases, it took some 140 men to pull a trireme along the ramp and into a shed. A superstructure of stone collonades, walls and tiled roofs covered the sheds, and a sophisticated fortification system of walls protected the entire base.

At the Battle of Salamis, Themistocles’ vision of a strong naval fleet for Greece would end up saving the young democracy and changing the course of history. Despite being severely outnumbered, with fewer than 400 warships against some 1000 Persian vessels, the Greeks managed to win decisively, halting the second Persian invasion of Greece. Two thirds of the ships that took part in the battle came from Athens, and were likely housed in the base Lovén’s team found.

“It is difficult to predict what would have happened if the Greek fleet had lost at Salamis, but it is clear that a Persian victory would have had immense consequences for subsequent cultural and social developments in Europe,” Lovén put it in the press release. “The victory at Salamis rightly echoes through history and awakens awe and inspiration around the world today.”

  1. REF ''Greek ancient naval base''

    Congratulations for your reference of the great news.

    Would though that the '' near of Athens'' is the well known City of Piraeus - port of Piraeus, the existence of which is not lesser than Athens.

  2. Truth is the Persians did land and burnt the ac Acropolis - this was not an invasion but punitive expedition as the Athenian mercenaries burnt the temple of Sardis during the Ionian revolt.
    Even had Greece been obsorbed by the Persians culturally little would have changed as the Persians had a system of rights of subject nations which is contained on a seal in the British museum.
    Persians paid for Jewish temple in Jerusalem,

  3. The Persian empire was not the slave empire of 300 fame , it was a cosmopolitan empire of different peoples who's rights especially religious were respected.
    Remember Themistocles when he was expelled from Athens lived the rest of his life with the Persian king and his daughter became an attendant at a Persian temple.
    The Persians were not intolerance or ignorant
    Contrary to what Hollywood wishes to portray.
