A seventeenth-century aristocratic palace set on the slopes of the Monsanto hillside in the western Sao Domingos de Benfica district of Lisbon, the Palacio Fronteira is one of the most architecturally distinguished surviving Portuguese country palaces of the wider late baroque tradition. The palace was completed in 1672 by the Portuguese nobleman Joao de Mascarenhas, the second Marquis of Fronteira, and has remained the principal residence of the wider Fronteira family continuously across the following three and a half centuries. The palace was originally conceived as a substantial new country residence for Joao de Mascarenhas following his receipt of the marquisate title in 1670. The Mascarenhas family had been one of the principal Portuguese noble families across the previous several centuries, with substantial military and diplomatic services rendered to the Portuguese crown across the previous Iberian Union period and the subsequent 1640 Restoration War. The substantial new palace was conceived as a deliberate dynastic monument celebrating the wider Mascarenhas family contribution to the Portuguese Restoration War. The palace is one of the most distinguished surviving examples anywhere in Portugal of the wider late baroque azulejo tile decoration tradition. The various external garden facades and the substantial internal rooms are decorated with continuous large-scale ceramic tile panels covering most of the available wall surfaces. The most famous panels are the Sala das Batalhas Battle Room cycle showing the principal battles of the 1640 to 1668 Restoration War and the Galeria dos Reis King Gallery sequence showing the principal Portuguese kings from the original 1140 foundation through to the late seventeenth century. The wider garden complex around the palace is one of the principal surviving formal Portuguese baroque garden compositions. The principal garden elements include the famous Casa do Fresco summerhouse pavilion at the eastern end of the central garden, the principal central tank with the substantial seventeenth-century tile-decorated retaining walls and the various formal box parterres with various sculptural fountains throughout the wider garden compound. The palace and garden complex remain in the continuing private ownership of the wider Fronteira family. The principal current owner is Fernando Mascarenhas, the twelfth Marquis of Fronteira and Alorna, who oversees the wider Fundacao das Casas de Fronteira e Alorna charitable foundation that operates the palace as a private museum. The palace is open to the public for guided tours each Monday through Saturday morning throughout the year, with the standard visiting route covering both the principal interior rooms and the formal garden complex.
