That is a true event… every September (second weekend) the island of Spetses celebrating Panaghia Armata (‘Virgin Mary of the “Armata’) and commemorating the great Naval Battle of Spetses (September 8, 1822).
The Armata Festival was established in order to commemorate the major victory of the naval forces of Spetses against the Ottoman fleet during the Greek War of Independence in 1821. This great exploit was achieved thanks to the act of bravery of the Spetsiote Captain Kosmas Barbatsis, who, with his fire ship, set fire on the Turkish flagship, which was blown up. This act of heroism is re-enacted every September, with dramatizations of this victory.
The celebrations culminate by burning a replica of the Turkish flagship, followed by a wonderful show of fireworks and music. A rather phantasmagoric spectacle, which the children will adore!
The festival also includes several other festivities such as traditional dances, concerts, theatrical performances, athletic events. There is also a special mass, which takes place at the church of Panagia Armata, which is located at the Old Harbour and at the church of St. Nicholaos, which is the Metropolis church of Spetses.
Have a look at how Armata Festival looked like in 2013:
