Basílica de San Francisco el Grande

A neoclassical basilica crowned by the largest dome in Spain, with chapels and a sacristy hung with paintings by Goya and Zurbarán.

A dome you have to back across the plaza to see whole

The Basílica de San Francisco el Grande is built around the largest dome in Spain: 33 metres across, 58 metres high, and the fourth largest in Europe after St. Peter’s, the Pantheon in Rome and Florence’s cathedral. It is genuinely difficult to photograph, and the only workable position is out in Plaza de San Francisco, stepping back as far as the square allows to fit the whole structure against the sky.

The building is a late-18th-century neoclassical statement piece. Design began in 1761 under Francisco Cabezas, was developed by Antonio Pló, and was completed under Francesco Sabatini — the Italian-trained architect behind the Puerta de Alcalá and major additions to the Royal Palace — with construction wrapping up between 1776 and 1784. A round central nave wrapped by six vaulted side chapels beneath that dome was a real engineering statement for the period, deliberately measured against the Roman and Florentine domes that inspired it. Each of the six chapels is decorated differently, ringing the rotunda; walk the full nave to see the dome from directly underneath, which is the only way its scale registers.

The Franciscan story on this site runs far deeper than the standing structure. Tradition holds that Saint Francis of Assisi founded a hermitage here in 1214 while passing through Madrid on his way to Santiago de Compostela, which makes this one of the oldest continuously religious sites in the city even though the building above it is 18th century. Pope John XXIII granted it basilica minor status in 1963.

Goya put himself in the crowd, and Zurbarán filled the sacristy

The art is the reason to make the trip, and it is the part that gets left out of general Madrid guides.

The Chapel of San Bernardino holds Francisco Goya’s “Saint Bernardino of Siena Preaching Before Alfonso V of Aragon,” commissioned in 1781 and one of his earliest major religious commissions. Goya reportedly painted himself into the scene as a spectator in yellow, which is the kind of detail worth knowing before you stand in front of it rather than after.

The sacristy is the bigger surprise: 49 large canvases on the life of Saint Francis, by artists including Francisco Zurbarán and Alonso Cano. That is a significant collection of Spanish religious painting outside the major museums, and it is here with essentially no queue — the case for coming if you want real Goya and Zurbarán without the Prado crowds. On the way through, look at the choir stalls, intricately carved and almost universally skipped by visitors focused on the dome and the headline Goya.

Interior photography of the artwork, the Goya in particular, is typically restricted or needs permission. Shots of the architecture itself — the nave, the dome from below — are generally fine, but ask staff on arrival rather than assuming.

Closed more than it is open: planning around the schedule

Hours are the single thing that ruins visits here, and they are not intuitive.

The museum visit, which is what gets you the chapels, sacristy and dome area, runs Tuesday to Saturday 10:30am–12:30pm and 4pm–5:30pm in winter (October to June), and Tuesday to Friday 10:30am–2:30pm in summer (July to September) — mornings only, and no weekends at all in summer. Church-only visits run roughly 8–10:30am daily, with Sundays 10am–1:30pm and 6:30–8pm for services. Hours also shift around the liturgical calendar, so a call ahead on +34 91 365 38 00 is worth it before making a special trip.

Entry to the museum and dome area is about €6, reduced to around €3.50 for groups, pensioners, students and disabled visitors. Thursdays are free, which makes this one of the better free art stops in central Madrid when the schedule lines up. No advance booking is needed — this stays genuinely uncrowded even at weekends, simply because it sits off the main tourist circuit. The strategy here is entirely about timing, not queues: aim for a weekday late morning right after the 10:30am opening.

Allow 45 minutes to an hour, less if you skip the museum sections and only see the church. Modest dress is the informal expectation at an active church. The unheated stone interior is properly cold in winter — keep your jacket on throughout. There are some steps at the entrance and the building is not fully modernised for wheelchair access, so contact ahead if you need arrangements. The dome’s scale impresses most ages, but the dense religious art and museum pacing suits older kids and teens better than toddlers.

Downhill into La Latina afterwards

The basilica sits in La Latina, one neighbourhood removed from the Royal Palace and Plaza Mayor circuit — which is precisely why it stays under-visited despite its scale — and the steep tapas-bar-lined streets around it are among Madrid’s best for an afternoon of wandering and eating. There is no café or gift shop of note inside, and there is no need for one.

Head straight for Cava Baja, La Latina’s best-known tapas street and arguably the single best crawl in the city, a few minutes away. If your visit falls on a Sunday morning, El Rastro sets up nearby and the two combine into a natural half-day. Plaza Mayor is a 10-minute walk back uphill, which makes the basilica a sensible detour on a longer loop through the historic centre rather than a dedicated trip. For a proper sit-down meal rather than tapas, Sobrino de Botín is in the same direction, between here and the square.
