The chapel is one of three locations in Goa, alongside
Chandor and
Reis Magos, where the feast of the Three Kings is celebrated with significant local tradition. The event marks the end of the
Twelve Days of Christmas. In Cansaulim, the celebration serves the three neighboring villages of Cansaulim, Arossim, and Cuelim. During the feast, three boys aged between 8 and 12 are selected from the three villages to portray the kings. They travel on horseback through different paths across the hill, eventually meeting at the chapel for a high mass. The boys dress in royal attire, wearing crowns and gowns, and are accompanied by a procession of locals and brass bands. They then leave the chapel and take a tour to the Saint Thomas Church, stopping at multiple points for both, blessings and rest. After a ceremony at the church, they take multiple routes back home, in commemoration of the different routes taken by the Three Kings. The feast is organised by the "vangodds" of the
gauncars (indigenous people) from the three villages who helped build the early church. ==Location==
