After King Dom Carlos I of Portugal and his heir apparent, Prince Royal Dom Luís Filipe, Duke of Braganza, were murdered in Lisbon, the estate had its main gates closed and standards lowered in mourning. João Pacheco de Sacadura Botte, at the time lord of the estate, personally knew the deceased king, and had hunted with him on occasion. After the proclamation of the Republic in Portugal, the estate continued flying the flag of the Kingdom of Portugal, as opposed to the new Portuguese Republic's flag, for decades. It also served as headquarters for Sacadura Botte's several unsuccessful campaigns to galvanize the Beira region into supporting attempts to restore the Monarchy.
