The festival involving the burning of effigies known as "Ninots" in Spain is Las Fallas, celebrated in Valencia. Held every March, this festival culminates in a grand display of fireworks and the burning of elaborately designed effigies representing social or political figures. The tradition symbolizes the arrival of spring and serves as a form of artistic expression and satire. The festival features parades, regional food, and lively gatherings, where the community comes together to celebrate creativity and the fleeting nature of art.
