Every 15th of May, Madrid comes alive with colour and tradition to honour its patron saint: San Isidro Labrador. But beyond the celebrations in the Pradera, the city is full of hidden corners that tell the story of his life and miracles. Let us take you on a route through the places that shaped his legend—perfect for curious travellers and lovers of all things authentically madrileño. And yes, it starts just a few steps away from Hotel Quatro Puerta del Sol.
San Isidro Museum. The origins of Madrid
Our journey begins in La Latina, the neighbourhood where San Isidro was born, lived, and died. Today, the San Isidro Museum stands on the very site of the Vargas family home—his employers. Inside, you’ll find an archaeological exhibition covering Madrid’s history and the famous “Miracle Well”, where Isidro is said to have saved his son from drowning. The story later inspired a painting by Alonso Cano. The chapel, decorated by Zacarías González Velázquez in the 18th century, stands where the saint once lived.
Church of San Andrés and the Bishop’s Chapel
Right next to the museum, the Church of San Andrés housed the saint’s remains for centuries. Nearby, the beautiful Bishop’s Chapel was built in the 16th century specifically to hold his body. Here began a historic tug-of-war between the church and the Vargas family over the custody of the saint’s remains—eventually leading to the creation of another Baroque chapel inside the church.
Royal Collegiate Church of San Isidro
With its striking Baroque façade and Jesuit roots, this church became the resting place of both San Isidro and his wife, Santa María de la Cabeza. It served as Madrid’s cathedral until the Almudena was completed and still maintains a solemn, sacred atmosphere today.
Almudena Cathedral
Although the Almudena is dedicated to the Virgin Mary, San Isidro also holds a place of honour here. In the apse, you can see the medieval chest that once held his remains, decorated with scenes from his miracles. The cathedral’s museum also preserves the 13th-century Codex of San Isidro and the original keys to his tomb. A must-visit for those interested in learning more about his life.
La Cuadra de San Isidro
A hidden gem: the Chapel of San Isidro, known as “La Cuadra”, can be found in Calle Petril de San Esteban. It stands where the saint kept his oxen and is only open to the public on 15th May. If you’re lucky enough to be in Madrid on that date, don’t miss it.
Hermitage of San Isidro and his miraculous spring
In Carabanchel, near the Manzanares river, lies the Hermitage of San Isidro. It was built on the site where, according to legend, Isidro struck a rock with his staff and water gushed out to quench his master’s thirst. These waters were believed to be miraculous even in the time of King Philip II. Although the fountain is only accessible during the May festivities, the surrounding nature is worth a visit all year round.
Pradera de San Isidro
No San Isidro trail is complete without a visit to the pradera, or meadow. Over 35 hectares of open space where locals gather to celebrate with music, picnics and the traditional rosquillas—choose between glazed (listas), plain (tontas), or topped with meringue (de Santa Clara). A vibrant tradition that has lived on since the 17th century.
Other historical corners
San Isidro’s presence is felt all over Madrid: a medieval well in the Iván de Vargas Library, a sculpture on the Toledo Bridge, and another in the gardens of San Francisco El Grande. Even Calle del Águila marks the spot where he was born. The city lovingly preserves the memory of its patron saint.
