Palace of Mafra

The complex is arranged on a strict central axis with the church occupying the centre and the convent and palace wings stretching out behind a long principal front that faces the town. The main façade runs approximately 220 metres and is flanked at each end by a square tower capped with a bulbous dome. The whole ensemble sits beside the royal hunting grounds known as the Tapada and was built mainly of local limestone, with extensive use of marble and fine woods in the interiors.

Measured figures underline the building’s scale. The footprint is reported at roughly 40,000 square metres in one account and 37,790 square metres in another. Interior counts list about 1,200 rooms, just over 4,700 combined doors and windows, and some 156 stairways. These numbers reflect the palace’s dual purpose as grand royal apartments and a large friary complex with many service and ceremonial spaces.

The basilica (major church) stands along the central line and is laid out in the form of a Latin cross, with a total length near 63 metres, a width of roughly 16.5 metres and a nave rising to about 21.5 metres. A dome sits over the crossing and reaches a reported height of 70 metres to the lantern. The church towers rise to about 68 metres and their form was inspired by the towers of Sant’Agnese in Agone in Rome. The interior is richly lined with rose and white marbles and displays fluted Corinthian semicolumns and sculpted altarpieces made from jasper.

The site contains two large historic carillons that form a distinguished bell ensemble. Accounts differ on the exact number of bells, reporting either 98 or 92 in total, and the bells were cast in Antwerp. The basilica also houses a rare set of six pipe organs, four of them placed around the transept (the arms of a cross-shaped church). These organs were built between 1792 and 1807, feature partially gilded Brazilian wood cases, and include pipes up to six metres tall.

A long Rococo library occupies the rear of the palace’s second floor and measures about 88 metres by 9.5 metres with a ceiling height of 13 metres. It contains two tiers of wooden bookcases and a patterned marble tile floor in pink, grey and white. The library’s holdings are reported variously as around 30,000 rare volumes and as more than 36,000 leather-bound books. Bats live in the library and provide an ecological service by feeding on insects that might otherwise damage bindings.

Behind the church and palace the friary is arranged around a rectangular plan with long corridors and multiple floors of cells. The complex was intended to accommodate several hundred friars, with capacities cited at about 300 to 330. A local School of Sculpture established during the building phase produced many of the marble statues and the jasper altarpieces found in the church, and the building’s decorative program includes numerous Italian sculptures and a major collection of 18th-century religious paintings by artists such as Agostino Masucci, Corrado Giaquinto, Francesco Trevisani and Pompeo Batoni, together with works by Portuguese artists trained in Rome.

Conservation work has left much of the principal fabric in a restored state. The national heritage authority has carried out recovery programmes, including cleaning and repair of the main façade, and the organ restoration project completed in 2010 received international recognition. Monuments, furnishings and movable liturgical treasures remain part of the palace’s preserved ensemble.
