The Spanish capital Madrid welcomes us with grand plazas and sparkling fountains. First stop is the Prado, one of Europe’s great museums and home to Goya, El Greco and Velázquez. We tour El Palacio Real, the seat the Spanish empire, and the Monasterio de las Descalzas Reales, a fascinating hoard of art treasures hidden away in the center of the city. After dark we sway to the rhythms of Flamenco dancers and lose ourselves in Madrid’s pulsating nightlife. Then we day-trip to the imperial city of Toledo to roam the twisting streets and narrow alleyways of this historic center. Tips on traditional food and jewelry.
