Fiestas de San Isidro (Festival of San Isidro) fills Madrid, Spain each May to honor San Isidro Labrador, the city’s patron saint, with lively open-air concerts, processions, and chulapo/chulapa costumes. Locals picnic at Pradera de San Isidro, sip limonada (wine-and-lemon punch), and dance the chotis before joining the pilgrimage to the Hermitage of San Isidro to visit the shrine and fountain. Evenings often end with fireworks and neighborhood street parties that capture true Madrileño pride.
