The Alexandrion (Greek Αλεξάνδρειον), a building of the international "Alexander the Great Institute", is a private institution of Macedonians living abroad. These Greeks, who came from Macedonia, had the idea to erect a monument in their homeland, at the foot of Mount Olympus, near the Temple of Zeus in Dion, a symbol of their bond with their homeland, and at the same time a place of encounter. It was founded in 1992. The head office of the Institute is in New York (USA), the local management is based in Katerini.
