Each area of the city has an organised group and they make Ninots which is Valencian for puppets or dolls. The Ninots take a long time to meke. Falles are displayed on many streets during the 4day festival. They have a contest and these Falles are burned in huge bonfires (except for the 1st prize doll) on the final day.
I went to only the last day of the festival. There was a parade too. It was so busy and noisy because of firecrackers. But everybody was having sooooo much fun! Great festival!
