The Real Basílica de San Francisco el Grande is a Roman Catholic church located in the historic center of Madrid. Constructed in the late 18th century, it is most notable for its massive dome, which measures 33 meters in diameter and remains the largest in Spain and the fourth largest in the world.
The interior is designed in a circular plan with six side chapels. It houses an extensive collection of Spanish art, including works by Francisco de Goya and Francisco de Zurbarán, as well as a significant series of paintings commissioned for the basilica's decoration in the 19th century.
The basilica was built on the site of a former Franciscan convent. King Charles III commissioned the project, with the initial design by Francisco Cabezas and later modifications by Antonio Plo and Francisco Sabatini.
During the 19th century, the church became a repository for significant religious art. The government commissioned various Spanish painters to decorate the chapels, resulting in a collection that serves as a survey of 19th-century Spanish academic painting.
The building was declared a National Monument in 1980. It continues to function as a parish church while operating as a museum that allows visitors to view its architectural features and art collection.
The basilica serves as a landmark of Neoclassical architecture in Madrid. Its dome represents a significant engineering achievement of the 18th century, and the church is central to the city's religious and artistic heritage, preserving a unique concentration of Spanish masters in a single ecclesiastical space.
Scholarly debates and areas of uncertainty
There is ongoing discussion regarding the structural integrity of the dome and the attribution of certain minor decorative elements within the side chapels, as the construction process spanned several decades and involved multiple architects.
