Falles (in Valencian) are a Valencian tradition which celebrates Saint Joseph's Day (19 March) in Valencia, Spain. The term Fallas refers to both the celebration and the monuments created during the celebration.

Each neighbourhood of the city has an organized group of people, the Casal faller, that works all year long holding fundraising parties and dinners, usually featuring the famous speciality paella. Each casal faller produces a construction known as a falla which is eventually burnt. A casal faller is also known as a comissió fallera. (wikipedia)
