It is one of the most deeply-rooted festivals and typical of the village.
On the 15th May a local holiday is celebrated in Puebla de Alcocer. The day begins with the departure of San (Saint) Isidro from the Convent of San (Saint) Francisco in a procession to the chapel of La Laguna (The Lagoon).
A procession is accompanied by many neighbours and several floats exhibiting typical extremaduran representations which are made by the local community.
Once the procession has finished, Holy Mass is celebrated and subsequently, there is a pilgrimage in the complex of San (Saint) Isidro, by the lagoon, where there is also an orchestra and children´s games.
