Cofradías are religious brotherhoods or associations in Spain, primarily associated with the Catholic Church. They play a significant role in organizing and participating in religious events, particularly during Holy Week (Semana Santa). Members often wear distinctive robes and carry religious images in processions, reflecting their devotion and community spirit. These organizations date back to the Middle Ages and serve various purposes, including charitable work and the promotion of faith. Each cofradía typically has its own patron saint and specific traditions, contributing to the rich cultural heritage of Spanish religious practices.
