Noche de San Juan in Las Palmas de Gran Canaria

Wow. I'd never seen a firework blast like this before

Every Year, Saint John's Eve is celebrated in the beautiful city of Las Palmas. It has something to do with the foundation of the city, although the idea that it was founded precisely on Saint John's day seems unlikely to me.

Anyway, the celebration is a part of "Fiestas Fundacionales", associated strongly with Saint John (i.e. San Juan) and is most certainly of pagan origin. It is basically a Midsummer midnight madness, except it is shifted by a couple days.
