San Sebastián Street Festival (La SanSe)

Each January, the cobblestone streets of Old San Juan become alive with color and sound during the San Sebastián Street Festival, popularly known as La SanSe.

This four-day celebration honours Saint Sebastian and Puerto Rico's rich heritage, marking the unofficial end of the world's longest holiday season. Visitors from around the globe gather to enjoy festive parades, live music, artisan markets and the warm hospitality of Puerto Rican culture.

Historical Background

The roots of La SanSe stretch back to 17th-century Spanish colonial processions, when enormous “cabezudos” were used to animate religious parades. In 1954, Father Juan Manuel Madrazo of San José Church re-established the fiesta as a modest parish commemoration on January 20th. By 1970, local historian Ricardo Alegría and community leaders revived the event to raise funds for education and foster civic pride. Over time, responsibility shifted from the Institute of Puerto Rican Culture to the Municipality of San Juan, ensuring professional staging and security. Except for cancellations in 2021 and 2022 due to COVID-19, La SanSe has thundered on each January since its modern revival.
