Following Alcácer Quibir, the palace was abandoned and, in 1629, it was acquired by Francisco Luís de Lencastre, 3rd high-Commendator (in Portuguese "Comendador-Môr") of the Order of Aviz, a descendant of infante George of Lencastre (natural son of King John II), and it was kept in the family for the next 300 years. Meanwhile, the family also inherited the title of Marquess of Abrantes.
