We have a lot !!!!
As I'm sure you all know well, Spain is a very "folklorical" country:
- New year's eve: is different in each country, here in Spain is the biggest party of the year, with family and fiends, at midnight, when the clock sounds (I don't know how to say it, sorry) we eat twelve grapes and make a wish. After that we go out to disco until the sunrise.

- On January 6th, we have the Three Wise Men's day, that's when children get their Christmas gifts and we visit our family and eat "Roscon de Reyes" wich is a cake filled in with cream and with little presents inside, one of them is a bean (if you find it you have to pay the cake) another of them is a little figure and if you find it (without breaking a tooth) you are crowned king ( the cake comes with a paper crown like the ones you get at McDonalds when you make your birthday party there, I know it's a bit stupid, but it's an ancient tradition...)

- Then on my town, Cartagena, on September, we have ten days of festival called "Carthaginians and Romans", as my english is not very good, here is something that I found about this:

The Murcian city of Cartagena presents the Carthaginians & Romans Festival, remembering its rich history with battle re-enactments, marches, a wedding, a circus and fireworks.
The festival opens with the lighting of a sacred fire and the inauguration of the Festival Camp beside the Estadio Municipal. Over the next ten days a period of history is relived, starting with declarations of enmity towards Rome, the wedding of Hannibal and Himilce, a Roman circus, chess tournaments and the declaration of war with the Romans.

The Carthaginians disembark in the port and start hiring mercenaries to help them fight, marching through the city to the Puente del Estadio. The following day the Romans arrive and throw themselves into battle. Following their win, they hold a victory procession through the town on the same route. The day after that they pay homage to those Romans who died in battle and another procession of troops takes place. The festivities end with the extinguishing of the sacred fire and a big fireworks display

Of course in each town, village and city there are several festival like this, depending of their history.

- Easter in Cartagena is also one of the best is Spain:
The Easter processions of Cartagena are spectacles of order, light and colour that wendtheir way through the streets of the city during a ten-day period; from the Fridaybefore Palm Sunday to Easter Sunday. Eleven passional processions are organised bythe brotherhoods of Cartagena during these ten days. One of their main characteristics isthe way in which they try to tell the Easter story chronologically, something which makesthem different to the ones in the great majority of Spanish cities where processions takeplace at Easter.Four brotherhoods are in charge of the organisation of the processions of Cartagena.These are: the Christ of Succour (Cristo del Socorro), Christ on the Dais of Capture (Jesúsen el Paso del Prendimiento), Jesus the Nazarene (Jesús el Nazareno), and Jesus Resurrected(Jesús Resucitado). The oldest of these brotherhoods is that of Jesus the Nazarene, whoseorigins date back to the beginning of the 17thcentury.

You can search for "Holly week of Cartagena" and watch the pictures.

Of course there are more of them, but I think this is boring enough...
