Basilica of the Sacred Heart of Jesus, Mafra National Palace

Palace of Mafra (Palácio de Mafra)

The Palace of Mafra, also known as the Palace-Convent of Mafra and the Royal Building of Mafra, is a monumental Baroque and Neoclassical palace-monastery complex located in Mafra, Portugal. Its construction, initiated in 1717 under King John V and completed in 1755, was a consequence of a royal vow to build a convent if his wife bore offspring. The birth of their daughter, Infanta Barbara, prompted the commencement of this vast project, which was significantly funded by the immense wealth derived from the gold and diamond mines of colonial Brazil.

History and Construction

The initial plan was for a modest friary for thirteen Capuchin friars. However, the abundant flow of precious metals from Brazil transformed the project into a sumptuous palace alongside an enlarged friary. The German architect João Frederico Ludovice, who had studied architecture in Rome, was appointed director of the royal works. While Ludovice is considered the head architect responsible for the unified style, several other architects, including Carlos Baptista Garbo and António Ludovice (the architect's son), were involved. Construction spanned 13 years, mobilizing a daily average of 15,000 workers, with up to 45,000 at its peak, and required the presence of 7,000 soldiers for order. The complex, largely built of Lioz stone, covers 37,790 m² and features approximately 1,200 rooms.

The basilica and convent were inaugurated on October 22, 1730, coinciding with the king's 41st birthday, with eight days of festivities. The basilica was dedicated to Our Lady and Saint Anthony of Padua. Work continued on elements such as the lantern on the cupola until 1755, when the workforce was redirected to Lisbon following the devastating earthquake.

Architectural Features and Holdings

The imposing façade, measuring 220 meters long, is constructed from local limestone. At each end, square towers with bulbous domes are inspired by Roman Baroque architecture, particularly the towers of Sant'Agnese in Agone. The central church is built of white marble, flanked symmetrically by the royal palace. The basilica itself is cruciform, measuring 63 meters in length and 16.5 meters in width, with a nave height of 21.5 meters. Its interior is adorned with rose-coloured and white marble, featuring altarpieces in jasper and 58 marble statues commissioned from prominent Roman sculptors. Notably, the basilica houses six monumental pipe organs and two carillons comprising 98 bells, representing the largest historical collection of carillons globally.

The palace complex also includes a significant library, considered a highlight and rivalling the grandeur of the Melk Abbey library. This Rococo library, designed by Manuel Caetano de Sousa, is 88 meters long and contains over 36,000 leather-bound volumes dating from the 14th to the 19th centuries. The library is also known for its resident bat colony, which helps protect the books from insect damage.

Later History and Recognition

The royal family found the palace rooms too gloomy for permanent residence, though it served as a popular hunting retreat. During the French invasion of Portugal in 1807, the royal family fled to Brazil, taking some of the palace's finest art and furniture. Following the dissolution of religious orders in 1834, the convent was abandoned by the Franciscans and later assigned to the military. The palace was declared a National Monument in 1907. In 2019, the Royal Building of Mafra was inscribed as a UNESCO World Heritage Site, acknowledging its outstanding universal value.
