Mafra National Palace

This vast complex is among the most sumptuous Baroque buildings in Portugal and one of the biggest buildings constructed in Europe in the 18th century. Designed by the german architect João Frederico Ludovice, the palace was built symmetrically from a central axis, occupied by the basilica, and continues lengthwise through the main façade until two major towers. The structures of the convent are located behind the main façade. The building also includes a major library, with about 40,000 rare books.
