The most important festival on Spetses is Armata, which extends over the second week of September and includes mainly artistic events, such as traditional dances, theatrical performances, various exhibitions, and presentations.
 

This celebration reaches its highest on Saturday, when locals and visitors get together in order to celebrate the anniversary of the Spetses naval battle, occurred on September 8th of 1822. This battle was part of the 1821 revolution and constituted one of its most important fights.
 

There are dramatizations of this victory, performed by night. Real ships are used, and a model ship is built especially for the occasion, in order to be burnt in the sea among a massive firework display, which closes in a big manner the festive week.
