This building was built in the 18th century as Casa de Misericordia, an orphanage and poorhouse. The patron of the city, Ramon Pignatelli, promoted its construction. During the War of Independence this building became a military hospital. In the 70s it was a college and in 1983 was renovated and became the seat of the Government of Aragón. In the centre stands the golden dome of the old church which is now a function hall. Interestingly, while it was an orphanage the building was maintained by the money collected from bullfights.
