Matadero Madrid
After sitting derelict for decades on the edge of town, the city’s slaughterhouses, with their stunning early-20th-century neo-Moorish architecture, have been reborn as Madrid’s most cutting-edge mixed-use arts complex for exhibitions, design, theater, film, and assorted festivals. This is a fantastic place to spend the day with young ones: surrounding the pavilions are terrace cafes, skate zones, and other activities for children.
