Capital of Ionian Kefalonia
Argostoli is the capital of Kefalonia, the largest Ionian island, served by Kefalonia International Airport and a sheltered harbor on a lagoon. Loggerhead sea turtles are often seen in its bay.
Argostoli became the island's capital under British rule in the 19th century, replacing older Assos. Like much of the island, it was rebuilt after the devastating 1953 Ionian earthquake.
