The Fallas festival started in medieval times when artisans would burn broken wood and artifacts from the winter at the spring equinox. Over time, figures called ninots were added to the fires and the festival date was moved to coincide with St. Joseph's Day. Nowadays, the large papier-mâché and polystyrene monuments can be over 30 meters tall and depict topical themes. Events include the daily despertà wake up calls with firecrackers and music, the plantà when monuments are erected, mascletà firecracker displays, and the final night of cremà when all the monuments are burned.
