Located five kilometers outside Argostoli and towards Pessada, you come across the Mazarakata Tombs, found in the early 20th century. The cemetery was excavated by accident by Colonel De Bosset searching for limestone to coat the roads.

The archaeologist Panagis Kavadias from Kefalonia was excavating on the tombs of Mazarakata from 1899-1909 and until the early 20th century he had searched the four tombs discovered by De Bosset and he brought into light another 12 tombs and 83 burials. Beneath the tombs and caves were roads through which they transferred the dead.  The 17th tomb was accidentally discovered in 1951 by the archaeologist Spyros Marinatos from Kefalonia.

The cemetery, which was found intact, is of great importance, it is the largest cemetery of the Mycenaean period the ruins of the Mycenaean era, witness to the culture that flourished in this region. Many reports were held in the books of Homer about Kefalonian cemeteries, and after what came to light, they seem rather confirmed. De Bosset donated some of the findings to Switzerland, the rest of the haul of Mycenaean vases and small art crafts were shared out between the archaeological museums in Athens and Argostoli.
