These extended across the present-day districts of Castelo de Vide and Nisa[1] and into territories near Valencia de Alcántara that now lie in Spain.[31] In 1232, Sancho II of Portugal donated further extensive domains south of the Tagus around Marvão and Portalegre to the Knights Hospitaller, along with the duty to fortify the frontier and help in its repopulation. The Hospitallers would dominate the administration of the region for two centuries, moving their Portuguese headquarters from Leça in Northern Portugal to nearby Crato in 1340. Much of the architecture to be admired today in Marvão can be attributed to the guiding hand of the Hospitallers in extending the castle and village in the 13th-15th centuries.
