A nice UNESCO cover from my country, Portugal, with a complet set issued in 2017 dedicated to the Royal Building of 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 located in Mafra, Portugal, some 28 kilometres from Lisbon. Construction began in 1717 under King John V of Portugal and was completely concluded in 1755. The palace was classified as a National Monument in 1910 and was also a finalist in the Seven Wonders of Portugal. On 7 July 2019, the Royal Building of Mafra – Palace, Basilica, Convent, Cerco Garden and Hunting Park (Tapada) was inscribed as a UNESCO World Heritage Site.
