This splendid 16th-century building stands on the grand Plaza del Pilar, across from the basilica. La Lonja is the historic marketplace of Zaragoza, where merchants carried out their trading and other commercial transactions.

 Designed by Juan de Sariñena, the edifice is the city's best example of Aragonese Renaissance architecture.

The building, constructed in brick, features a rectangular plan and a decorative facade with rows of uniform arched windows and depictions of the kings of Aragón in medallions.

 The interior holds the building's most impressive features—a series of stone columns, which were sculpted from the remains of the city's former Roman walls. Created by Juan de Segura, the columns turn into defined arches, appearing to turn into palm trees
