The Palácio Nacional de Mafra palace complex covers 40,000 square meters and has 1,200 rooms. Visitors can admire the monumental and decorative interior of the church, the post-Franciscan monastery and the delightful palace. Particularly noteworthy is the Rococo room made of marble, which houses the library. There are many valuable copies of books, e.g. the Bible from 1514. Also worth seeing is the dazzling throne room, yellow music room, queen's bedroom, trophy room, and great hall.
The palace and monastery complex with the church was built in the first half of the 18th century. It combines elements characteristic of the Baroque style and Italian Classicism. Construction works were entrusted to German architect Johannes Friedrich Ludwig. It was a votive offering of King Jan V for the birth of the long-awaited heir to the throne. The monastery was the seat of the Franciscan order. The basilica was consecrated in 1730 and services were held there. The palace was the residence of the royal family. In 1910, after the collapse of the Portuguese monarchy, a museum was created in the complex.
