Assos Castle is located in one of the highest areas of Kefalonia, which attracts visitors in large numbers to enjoy the beauty of the surrounding nature of lush green trees, the charming view of the sea on the horizon, the archaeological remains and stone arches remaining from the original building. The castle is an open museum for people interested in history and archeology, as it was built as an impenetrable fortress that protects the island from the attacks of pirates and invaders, and today it has become one of the most important monuments on the island, where the largest part of it is still standing.
