Grand Royal Palace is a complex of three historic buildings on Plaça del Rei. They were once home to Aragon kings. The oldest section is St. Agatha Chapel constructed at the start of the 14th century. Saló del Tinell was commissioned by Peter IV of Aragon during his reign from 1336 until 1387. Finally, Charles V – who was both King of Spain and Holy Roman Emperor during the mid-16th century – ordered the building of Palau del Lloctinent in 1549. These structures are part of the Barcelona City History Museum.
