The Marquis of Cerralbo left his palace to Spain on one condition: nothing moves. So nothing has. The result is the most atmospheric interior in Madrid — a time capsule of how the 1890s aristocracy actually lived, ballroom and billiard room and mirrored gala staircase included, five minutes from Plaza de España.
It takes an hour, costs €3 (often nothing — see the free slots), and pairs with the Temple of Debod sunset next door. Visitors consistently rate it above museums ten times its size.
The minimum you must see
01
The Ecstasy of St Francis — El Greco
📍 First floor, religious cabinet — the collection’s single famous picture.
02
The ballroom
📍 Main floor — mirrors, frescoes and the chandelier photographs never do justice to.
03
The armoury
📍 Main staircase landing — one of Spain’s best private arms collections.
04
The gala staircase
📍 Entrance — designed to make every guest feel underdressed.
Tips
Thursday evening free entry is the least-known quality free slot in Madrid.
Rooms are dim by design (conservation); give your eyes a minute per room and it becomes the point.
Questions, answered
Kids?
Surprisingly good — armour, secret-feeling rooms, one hour total. Better than any of the big three for under-10s.
Combine with what?
Temple of Debod at sunset (3 min walk) and dinner on Calle del Conde Duque side of Malasaña.
How much is a ticket?
€3 — and free Thursday evenings 17:00–20:00, Saturdays from 14:00 and all day Sunday.
What day is it closed?
Monday. Thursday is the long day, reopening 17:00–20:00 — Madrid’s least-known quality free slot.
How long do you need?
One hour covers the whole palace — it is small and dense rather than large and thin.
What is the nearest metro?
Plaza de España (L3/L10) or Ventura Rodríguez (L3), both about three minutes away.
