Free city museums in Madrid are not news to a visitor from Britain, where the national collections have charged nothing for decades. What catches people out in Madrid is that free does not mean open. Four city-run museums cost nothing at all, and on the same bank holiday Monday the Museo de San Isidro opens, the Ermita de San Antonio de la Florida closes, and the Temple of Debod opens only for those holding a session booked weeks earlier.
Are Madrid’s city museums free, and when do they open? All four charge nothing on any day of the year. They open Tuesday to Sunday, several cutting back an hour between 15 June and 15 September, and they close six fixed dates a year. Only the Temple of Debod requires a booking.
A city-run museum in Madrid is a building the Ayuntamiento de Madrid operates with free admission, temporary exhibitions included. Nothing needs booking except Debod, most visits take under an hour, and all four sit inside metro zone A, where a single fare is €1.50 to €2.00. What differs between them is the calendar. From five journeys the 10-trip Metrobús at €7.30 brings each one to €0.73, tap water is drinkable everywhere and free to ask for, and none of the four is close enough to a lunch hour to matter, since Spanish lunch runs from about 2pm.
Which of them opens on a bank holiday Monday
A bank holiday Monday decides a long weekend in Madrid, and the answer sits in each building’s published hours rather than in a network-wide rule.
| Museum | On a bank holiday Monday | Why |
|---|---|---|
| Museo de San Isidro | Opens | Its hours say “and public holidays” |
| Temple of Debod | Opens | But only with a booked session |
| Museo de Historia de Madrid | Closes | Weekly closure falls on Monday |
| Ermita de San Antonio de la Florida | Closes | Shuts Mondays, holidays included |
The Museo de San Isidro is the one that saves a long weekend, because its published timetable names public holidays explicitly. According to the Ayuntamiento de Madrid it runs 10am to 8pm, and 10am to 7pm between 15 June and 15 September, with last admission fifteen minutes before closing, at Plaza de San Andrés 2. The detail is in the Museo de San Isidro.
The Ermita de San Antonio de la Florida does the opposite and says so just as plainly, closing on Mondays including public holidays. It opens Tuesday to Sunday, 9.30am to 7pm, and reopened on 12 June 2026 after a €2.2 million restoration, covered in the Goya chapel.
The one that rations by capacity rather than by price
The Temple of Debod is as free as the rest and the hardest of the four to actually get into, because what it hands out is not a price but a place.
According to the Ayuntamiento de Madrid each month’s sessions are released on the 15th of the previous month, a booking covers up to 6 tickets, and the slot holds from five minutes before the assigned time until ten minutes after. Against an average visit of 30 minutes, that arrival window is half the length of the visit itself. The mechanism is in booking the Temple of Debod.
For a short trip that changes the planning order. Debod is the only one of the four that has to be fixed before the flight rather than on the day.
Why a state-owned chapel sits in a city network
The Goya chapel is not municipal at all, and that split explains why it appears on two different lists.
Patrimonio Nacional owns the Goya chapel, Madrid City Council has held its custody since 1987, and the Real Academia de Bellas Artes de San Fernando advises. Three institutions over one small building.
That split is what sets the fare. As a city-managed space it applies the network’s blanket free admission rather than the twelve conditional exemptions Patrimonio applies at its own sites, set out in the Madrid Royal Sites.
Which one to pick if there is time for only one
The Museo de Historia de Madrid holds the most quoted object in the network, a scale model of the city from 1830 measuring 5.2 by 3.5 metres at a scale of 1:432, inside a former poorhouse at Calle de Fuencarral 78. Its doorway by Pedro de Ribera, dated 1721-1726, stands on the pavement and needs neither ticket nor timetable, covered in the 1830 model of Madrid.
It opens Tuesday to Sunday, 10am to 8pm, cut to 7pm between 15 June and 15 September, and closes Mondays and six fixed dates. How this network fits with the free windows at the big museums is worked out in free museum hours in Madrid, and who sets which timetable across the city is in who sets Madrid’s opening hours.
Frequently asked questions about Madrid’s city-run museums
Are Madrid’s city-run museums really free?
Yes, all four charge nothing on any day of the year, temporary exhibitions included. What separates them is not price but calendar, and in one case capacity, because the Temple of Debod rations entry by timed session instead of by ticket.
Which Madrid museums open on a bank holiday Monday?
The Museo de San Isidro, whose published hours say “and public holidays”, and the Temple of Debod if you hold a booked session. The Museo de Historia de Madrid and the Ermita de San Antonio de la Florida both close.
Do you need to book a free museum in Madrid?
Only the Temple of Debod. Its sessions are released on the 15th of the previous month, a booking covers up to six tickets, and the slot holds from five minutes before your time until ten minutes after, then lapses.
Do Madrid’s city museums change hours in summer?
Several do. The Museo de San Isidro and the Museo de Historia de Madrid close at 8pm for most of the year and at 7pm between 15 June and 15 September. Last admission stays fifteen minutes before closing either way.
Why is the Goya chapel in a city network if the state owns it?
Because ownership and management are split. Patrimonio Nacional owns the building, Madrid City Council has held its custody since 1987 and the Real Academia de Bellas Artes de San Fernando advises. The city management is what makes admission free.
Four museums that cost nothing, four calendars, and the cheapest one is the hardest to get into.
