The Palau Moja is a stately neoclassical mansion on C/ Portaferrisa at the corner of La Rambla. Construction began in 1774 with the demolition of the old Rambla walls and the port Ferrissa, and opened its doors in 1784. The developer was Maria Lluïsa de Copons, wife of the Marquess Moja, and the arquitect in charge of the project was Josep Mas i Dordal, who also was in charge of La Basílica de la Mare de Déu de la Mercè, La Parròquia de Sant Vicenç de Sarrià and the Palacio Episcopal de Barcelona.
Throughout its history, the Palau Moja received marquesses (the Mojas and the Comillas), counts (Güell), monarchs (Alfonso XII and Juan Carlos I when he was a prince) and even distinguished figures in Catalan culture such as poet Jacint Verdaguer.
The building currently houses the offices of the Ministry of Culture, after being acquired and restored by the Departament de Cultura de la Generalitat.
