Museo de la Real Colegiata de San Isidoro, Museum in a medieval basilica in León, Spain

The Museo de la Real Colegiata de San Isidoro occupies the Basílica de San Isidoro in León and reopened in April 2024 after almost eight years of renovation. Its collection is centred on the Panteón de los Reyes, a burial chapel whose Romanesque frescoes earned it the name Sistine Chapel of the Romanesque. Among the other pieces are the 11th-century Chalice of Doña Urraca, the Arqueta de los Marfiles, the Portapaz del Pantocrator and the Arqueta de Limoges.

The building dates to the early days of the Christian church in Spain and served as an important center for León and its rulers over many centuries. After nearly eight years of restoration work, the museum opened to the public in 2024.

The museum's name comes from Saint Isidore, whose relics the collegiate church of León has kept since the 11th century, when King Ferdinand I and Queen Sancha moved them there. The Panteón de los Reyes holds the tombs of León's medieval rulers, and the Cáliz de doña Urraca, an 11th-century chalice, is displayed among the liturgical objects.

The museum is housed in quiet rooms with old stone floors and high vaulted ceilings that invite slow exploration and close observation of details. Plan to spend time there at a relaxed pace and check opening hours before visiting, as they may vary depending on the season.

The Panteón de los Reyes, the royal burial chamber, is nicknamed the Sistine Chapel of Romanesque art for its painted vaults. The museum also holds the 11th-century Cáliz de doña Urraca, the Arqueta de los Marfiles, the Portapaz del Pantocrator and the Arqueta de Limoges. After almost eight years of works, it reopened in April 2024.
