Things to Do in Aragón

Explore the underwater worlds of the Nile, the Mekong, the Amazon, the Ebro, and the Murray-Darling rivers at the Zaragoza Aquarium (Acuario de Zaragoza). This is Europe’s largest freshwater aquarium, offering over more than 5000 animals from 350 species, including Amazon-dwelling arapaimas and endangered iridescent shark catfish.

On the banks of the Ebro, Zaragoza’s colossal cathedral marks the spot that, according to tradition, Mary appeared to St. James in AD 40. Since then, the site has hosted many religious structures, with major restorations in the 12th, 15th, and 17th centuries. Today, the church is one of Spain’s most significant cultural attractions.
