"Pentolaccia Casamassimese" is the main event to attend during Carnival in the town and among the most important ones in the neighborhood. In 1977, during Carnival, there was the introduction of the first "Pentolaccia", in English called "piñata", a pot made of earthenware, hanging from a crane, which contains sweets and other objects loved by children. From that time on, a group of local artists started the first association with the purpose of building carnival floats and creations out of paper mache.
The "Pentolaccia" started being renowned at a regional level thanks to parades of carnival floats, dance exhibitions, masked groups and special guests during first weekend of Lent. This tradition, in 2012, has been awarded the High Patronage of the President of the Republic and since 2016 it's a component of the Ancient Carnivals of the Ministry of culture. It consists in a parade of paper mache carnival floats and masked groups, dance and singing performances, traditional parties in the dance halls and various types of entertainment.
