One of the many miracles of Saint Demetrios is the following. In 1823 AD Turks were stationed at the Acropolis of Athens preparing the ammunition to hit the Greeks with cannons who were in the 16th century Church of Saint Demetrios. The cannons were in the Propylaea of the Acropolis. Saint Demetrios saved the Christians however when the gunpowder exploded in the Turks' hands and destroyed part of the Parthenon. To remember this miracle, the church was called Saint Demetrios Loumpardiaris, from loumparda, which is the large cannon of the Turks that was destroyed.
This church is located off Saint Dionysios the Areopagite and Saint Paul Road. Many baptisms and weddings take place here.
