The Fallas (Falles; Fallas) is a traditional celebration held annually in commemoration of Saint Joseph in the city of Valencia, Spain. The five main days celebrated are from 15 to 19 March, while the Mascletà, a pyrotechnic spectacle of firecracker detonation and fireworks display, takes place every day from 1 to 19 March. The term Fallas refers to both the celebration and the Falla monuments (Falla, singular; Fallas/Falles, plural) burnt during the celebration. A number of towns in the Valencian Community have similar celebrations inspired by the original Fallas de Valencia celebration. For example, the bonfires of Alicante or the Fiestas de la Magdalena in Castellón de la Plana. The Fallas (Falles in Valencian) festival was added to UNESCO's intangible cultural heritage of humanity list on 30 November 2016.
Each neighbourhood of the city has an organised group of people, the Casal faller, that works all year long holding fundraising parties and dinners, usually featuring the noted dish paella, a specialty of the region. Each casal faller produces a construction known as a falla which is eventually burned. A casal faller is also known as a comissió fallera and currently there are approximately 400 registered in Valencia.
The name of the festival is the plural of the Valencian word falla. The word's derivation is as follows:
Latin fax (accusative facem), "torch" → Latin facula (diminutive; accusative faculam) → Vulgar Latin *faclam → Valencian falla.

Formerly, much time would be spent by the casal faller preparing the ninots (Valencian for puppets or dolls). During the four days leading up to 19 March, each group takes its ninot out for a grand parade, and then mounts it, each on its own elaborate firecracker-filled cardboard and paper-mâché artistic monument, in a street of the given neighbourhood.
