Proud to be the largest Orthodox Church in all of the Balkans with a capacity of 5,500 persons, Agios Andreas boasts exquisite architecture, beautiful paintings and great icons that adorn the interior. The church displays the skull of Saint Andrew as well as part of the cross he was crucified on. Interestingly, the old basilica is alleged to be at the exact spot where Saint Andrew was martyred. The same place was also where a temple to the ancient Goddess of Demeter existed.
