The Royal Collegiate Basilica of San Isidro is one of Madrid’s oldest churches. People also call it the Collegiate Church of San Isidro el Real. It stands at 37 Toledo Street, in the heart of Madrid’s historic center. The church holds deep religious and cultural meaning for the city.
From the 17th century, the basilica served a key purpose. It was the church of the Imperial College of the Society of Jesus. The Jesuits built it to serve both students and local worshippers. Even today, it connects to the former college building.
Over time, the basilica gained more importance. It became Madrid’s main cathedral for a while. That changed in 1993 when the Almudena Cathedral was consecrated. Still, the basilica remains a popular place of worship.
Many people visit because the basilica holds the remains of two saints. Saint Isidore, the patron saint of Madrid, rests here. His wife, Saint Mary of the Head, also lies beside him. As a result, many believers visit the site every year.
During San Isidro’s feast in May, thousands attend Mass and events. Locals and tourists gather in joy and devotion. Clearly, the basilica plays a big role in the city's religious life.
Architecturally, the basilica is impressive. It shows a Baroque style with rich detail and strong design. Despite changes over time, the church keeps much of its original charm.
Today, the Basilica of San Isidro is more than a building. It is a symbol of faith and heritage. It links Madrid’s history to its present. Therefore, it remains a cherished part of the city.
