The Prado and the Royal Palace are the headline acts, but a first-timer with a spare afternoon can add eight genuinely worthwhile stops without straying far off the standard route, most of them free. Two sit a short walk from the Royal Palace, one is a working Metro station frozen in 1966, and one is a chapel where Goya himself is buried under his own frescoes. If you’re basing yourself centrally, check rates on Booking.com so you’re within easy reach of most of these. Our things to do guide covers the headline sights; this list is what to add once you’ve done those.

The most beautiful free museum in Madrid
Cerralbo Museum is a 19th-century noble’s mansion, kept intact with its original furnishings, El Greco, Zurbarán, Tintoretto, and Van Dyck paintings on the walls exactly where the family hung them. It’s a five-minute walk from the Royal Palace area, permanently free, and skipped by most first-timers who don’t know it’s there, worth the detour on a Palace day.
Madrid’s original city wall, a block from the Cathedral
Muralla Árabe is roughly 120 metres of Madrid’s actual 9th-century Islamic fortress wall, still standing near Cuesta de la Vega behind Almudena Cathedral. It’s a five-minute add-on if you’re already at the Royal Palace or the cathedral, a genuine piece of the city’s Moorish founding hiding in plain sight, declared a National Monument in 1954.
Goya’s own resting place, under his own frescoes
San Antonio de la Florida is an 18th-century hermitage with a dome Goya himself frescoed in 1798, and his remains have rested here since 1919. A near-identical second chapel was built next door in 1928 so services could keep running without disturbing the original. It’s a quieter, lower-key Goya stop than the Prado, and free to visit.
Is the Chamberí ghost station worth the detour?
Yes, it’s one of Madrid’s best small museums and most first-timers have never heard of it. Andén 0 opened as a working Metro station in 1919, closed in 1966 because it sat on a curve too tight to lengthen the platforms, and reopened in 2008 as a free museum with original 1919 tile advertising and turnstiles intact. Live Line 1 trains still pass behind the glass while you’re standing there, a genuinely strange, atmospheric stop. Visits run on booked slots, check current availability on esmadrid.com before you plan a day around it.
Real Fábrica de Tapices and El Capricho, for a full offbeat afternoon
The Royal Tapestry Factory, founded 1721, still hand-weaves on 18th-century looms, Goya began his career here, and visits run by appointment on weekdays only, check current availability on esmadrid.com . El Capricho, built 1787-1839 for the Duchess of Osuna, only opened to the public in 1974 and keeps restricted opening days, part of why it stays one of Madrid’s least-visited green spaces. Browse a small-group Madrid walking tour if you’d rather have a local string these stops together for you.
One concrete tip
Pair Cerralbo Museum and Muralla Árabe with a Royal Palace morning, both add less than an hour each and sit within easy walking distance, then save the Chamberí ghost station or El Capricho for a day you’ve built around a slower afternoon.
