Alameda de Osuna

Residential Alameda de Osuna is centered on the remains of Alameda Castle, a 15th-century fortress and excavation site ringed by wooded paths. The castle was a command post in the Spanish Civil War, and a bunker from that conflict is preserved amid elegant landscaped gardens at Parque El Capricho. Nearby airport hotels have low-key bars, and neighborhood taverns serve classic Madrid tapas.
