The rocket war is an old custom of Vrondados that began since the time of the Turkish occupation and it still happens every year in the Easter.

Firstly the residents of the two parishes, Panagia Erithiani and Saint Mark's, which are facing each other, made extempore little cannons. But all these by the time became extempore rockets, fireworks made from niter, sulphur and gun-powder.

The preparation of the rockets starts immediately after Easter, so everything to be ready for the next year. The amount of the rockets the last years happens to be large, almost few thousands in number and the view of the rockets and the fireworks burning in the air, at the night of the Christ's resurrection, really magnificent and fascinating. And many people use to visit Chios Island this time of the year, so to enjoy this event that happens only here.

It is a unique experience but dangerous and for this reason, the last few years has been taken measures for the protection of all the people that attempt this event, so the custom to be continued.
