The Mafra National Palace is a monumental Baroque and Italianized Neoclassical palace-monastery located in Mafra, Portugal.
The palace, which also served as a Franciscan monastery, was built during the reign of King John V (1707-1750), in consequence of a vow made by the king in 1711, who promised to build a convent if his wife, the Queen Mary Anne of Austria, gave him descendants. The birth of his first daughter, the princess Barbara of Braganza, made the king initiate the construction of the palace.
This vast complex is among the most sumptuous Baroque buildings in Portugal.
