• Under-7s go free, but their tickets are only issued at the box office, not online
• Entrance is round the corner at Calle Marqués de Casa Riera 2, not on Calle de Alcalá
• A ticket does not include a table at the rooftop cafe-restaurant, which takes its own bookings

A rooftop 56 meters above Calle de Alcalá, reached by a glass-door lift from the lobby of the Círculo de Bellas Artes. Kids stand beneath the bronze Minerva, the Roman goddess of wisdom and the arts, who crowns the building, and look out across the city's skyline.

A cafe-restaurant runs on the terrace from breakfast until late at night.
