Magusto, Magosto, Magosta, Castanyada, or Festa da castanha () is a traditional festival in the Iberian Peninsula. It is popular in Portugal, Galicia and some areas of northern Spain, such as Cantabria, Asturias, Catalonia, and the provinces of León, Zamora and Salamanca and Cáceres, but also in some parts of the Canary Islands. The festival is also celebrated in both sides of the French-Spanish border. It has also spread internationally as a 'chestnut party'. Etymological origins are unknown, but there are several theories for the Magosto name: Magnus Ustus (great fire) or Magum Ustum (highlighting the magical character of fire).
