Zaragoza is a city of startling contrasts that sits on the banks of the Ebro River in Aragon, Spain. This regional capital came to the fore as the host of the 2088 World Expo, the event gracing the city skyline with some striking modern designs, including futuristic bridges and Europe's largest freshwater aquarium. Yet, the city's most iconic vision remains that of the Basilica de Nuestra Señora de Pilar, its many domes gleaming in the golden light of day, pondering the reflection of its ancient visage in the waters of the river below. The Palacio de la Aljaferia is another intriguing relic, its exquisitely painted ceilings and ornate carvings serving as remnants of the formidable wherewithal of the Moors. Alongside these high points are more modest treasures including Roman ruins, museums that celebrate the work of Francisco de Goya and a whole host of tapas bars. The past, present and future collide in Zaragoza for a rich, cultural melange that makes Spain's fifth-largest city a worthy contender for the coveted interest of tourists.
