The Ancient Acropolis of Ithaca, also widely known as the Acropolis of Alalkomenes, is situated at the peak of Aetos Hill, at the narrowest point of the island. This archaeological site is identified by many researchers and explorers as the "Castle of Odysseus," infusing the location with a legendary aura that captivates every visitor. Due to its commanding position, the acropolis held absolute control over the passages between northern and southern Ithaca, as well as the marine channels between Ithaca and Kefalonia.

The site preserves the remnants of a significant fortified city that flourished primarily during the Classical and Hellenistic periods. Its most striking feature is the famous "Cyclopean walls," constructed from massive, finely carved stone blocks that fit together perfectly without the use of mortar. Archaeological excavations have brought to light the foundations of ancient dwellings, religious sanctuaries, and water cisterns, alongside numerous artifacts-including ancient coins bearing the figure of Odysseus-proving the city's economic and cultural prosperity.

Hiking up Aetos Hill to reach the ruins is a remarkable experience for trekking enthusiasts and history buffs alike. Although the rocky path is steep and requires careful footing, the reward at the summit is unparalleled. Visitors are greeted by a rugged, pristine landscape and a breathtaking, 360-degree panoramic view that encompasses the entire island of Ithaca, the vast Ionian Sea, and the coastlines of mainland Greece, beautifully bridging epic myth with historical reality.
