The Ionian Sea, with its crystal-clear waters and abundant marine life, is one of the most captivating maritime areas in the Mediterranean. From antiquity to the present, it has consistently served as a crucial corridor for commercial and military activity, acting as a crossroads of civilizations and political powers. Beyond its unparalleled natural beauty, the Ionian Sea also hosts a series of historical shipwrecks that not only serve as underwater museums but also offer enchanting diving experiences while significantly contributing to marine biodiversity.
Kefalonia, the largest of the Ionian Islands, is no exception. Its strategic location and the unstable weather conditions of the Ionian have resulted in a multitude of shipwrecks, many of which hold great historical value. This is why ancient and historical shipwrecks are protected by national legislation and international cultural heritage protection authorities. These underwater monuments, as they can otherwise be characterized, tell stories of wars, trade routes, and personal tragedies.
Shipwrecks and reefs serve as refuges and sources of nourishment for many marine species, significantly contributing to marine biodiversity. In other words, these underwater monuments of history are precious ecosystems. However, these same shipwrecks also become deadly traps due to lost fishing nets that often get entangled on them, trapping sea turtles, dolphins, seals, and fish—creatures that cannot free themselves and eventually die.
Focusing more closely on the shipwrecks in Kefalonia, it is worth clarifying from the outset that although dozens of ships and submarines lie on the seabed, the vast underwater museum is immense, and the deep waters of the Ionian, combined with the construction and formation of the ships, make research quite challenging.

Below are some of the most impressive and culturally interesting shipwrecks on the island that have rightfully attracted the interest of researchers and diving tourists.
The Shipwreck of the Perseus
One of the most famous shipwrecks in the area is that of the British submarine "Perseus," located at a depth of 52 meters between the islands of Kefalonia and Zakynthos, built in 1928. The submarine sank after hitting a mine during World War II. The only survivor, British Petty Officer John Capes, escaped through the submarine's escape hatch and managed to swim 8 kilometers to Kefalonia. There, the locals hid him from the occupiers for 18 months until he was smuggled to Smyrna, earning the British Empire Medal. In the summer of 2020, six specially trained volunteer technical divers from the Ghost Diving team conducted a cleanup mission of the wreck. Their goal was to remove the fishing gear that had covered the submarine, thereby protecting the area's marine life.
The Shipwreck of the "ARDENA"
The "ARDENA," a ship built in 1915 in Britain, was used during the Greco-Italian War for military transport. During World War II, the ship was commandeered by the Germans and used to transport Italian prisoners. On September 28, 1943, an explosion sank it near the entrance of Argostoli Bay, with a tragic toll of 720 Italian prisoners' lives. The exact circumstances of the sinking remain unclear, with possible causes being either intentional sinking by the Germans or striking an Italian mine.
The Roman Shipwreck with Thousands of Amphorae
In Fiskardo, Kefalonia, a 2,000-year-old Roman shipwreck was discovered, one of the four largest shipwrecks ever found in the Mediterranean. The ship, 34 meters long and 13 meters wide, was found in excellent condition using sonar, revealing thousands of amphorae and other ceramic vessels intended for transporting food and wine. The amphorae, numbering approximately 6,000, provide valuable information about Roman trade and shipping routes of the era. This discovery, dating between 1 BC and 1 AD, offers new insights into shipbuilding and the commercial practices of the Roman Empire, shedding light on significant aspects of trade history in the Mediterranean.
Diving Tourism in Kefalonia
Kefalonia, with its crystal-clear waters and wealth of shipwrecks, has evolved into a top destination for diving tourism. The combination of natural beauty, historical significance, and the variety of dive sites makes it ideal for divers of all levels. The historical shipwrecks that "adorn" the seabed of the Ionian Sea play a significant role, offering unique experiences that allow divers to explore remnants of another era up close.
A few years ago, the Ministry of Culture, recognizing the importance of these underwater treasures, allowed organized and guided dives at many of the country’s shipwrecks. In the case of Kefalonia, the three shipwrecks that have become accessible are the submarine Perseus, the SS Ardena, and the Carinthia V.
The decision to create underwater museums and the strict monitoring of diving activities ensure that these historical sites will remain intact for future generations.
Kefalonia and the Ionian Sea as a whole are true treasures for sea and history enthusiasts. The historical shipwrecks of the area tell fascinating stories of wars, explorations, and human endurance. The richness of these shipwrecks is not limited to the history they narrate but also includes their valuable contribution to underwater biodiversity and the environment. From antiquity to World War II, the Ionian shipwrecks reveal a variety of commercial, military, and cultural elements that provide deep insights into the past and a unique environment for present marine life. Diving tourism in Kefalonia, in turn, offers unique experiences as dives reveal the stories hidden beneath the waves. The journey into the underwater world of Kefalonia is not just an adventure but also an opportunity to discover and keep history alive.
