More than a million marigolds fly through the air at the traditional Battle of the Flowers, at the end of every July.
The annual event marks the close of Valencia's July Festival and is free for anyone to see (apart from some seating areas that must be reserved and paid for).
Elaborately decorated floats pass up and down the Paseo de la Alameda in the city centre, as crowds throw flowers at their occupants.
They in turn attempt to defend themselves with tennis rackets and other improvised shields, whilst returning fire with more orange and yellow blossoms.
The flowers are grown in fields around the city especially for the celebration and the floats are designed and decorated in the famous Valencian style of Las Fallas, with incredible sculptures and passengers in colourful traditional costumes.
If this event doesn't seem messy enough, why not go to the Tomatina tomato fight instead?
