While we wouldn't put Zaragoza, the capital of Aragon, on a must-see list, it does have a few things that may pique your interest. You can visit the Aljaferia, an 11th-century Moorish palace, as well as two world-class museums, each housed in a restored palace: Museo Pablo Gargallo (dedicated to the sculptor) and Museo Camon Aznar (artworks). Roman walls, churches (such as Basilica de Nuestra Senora del Pilar) and other museums (including the Sacristy and Tapestry Museum and Museo Provincial de Bellas Artes) complete the picture. 170 mi/275 km northeast of Madrid.
