During the context of the Christian Reconquest of the region, the fortress and a few others in the regions belonged to a man named Chamoa Rodriguez. At the time of the Christian Reconquest, here existed a castle, which together with others in the eastern border region, belonged to D. Chamoa Rodrigues, who donated, through his aunt, the Countess Mumadona Dias, the Monastery of Guimarães. Retaken by Muslim forces in 1000, the village was later devastated by the brothers Tedom and Rausendo Ramires in 1030, only to be reconquered by Fernando Magno in 1055 or 1056. In this period, the castle is among the inventoried property belonging to the Monastery of Guimarães in 1059. With the independence of Portugal, Afonso I of Portugal donated his dominions to his brother, Ferdinand Mendes de Bragança. The noble, on 8 July 1130, granted a charter to the town and promoted the rebuilding of the castle. Later, under the reign of Afonso's son and successor, Sancho I, massive works of recovery of the walls and the erection of the main tower were completed as epigraphic inscription dated 1189. Under the reign of King Sancho II, the areas of Numão and its castle were donated temporarily to April Peres Lumiares. In October 1265, Afonso III confirmed the charter to the village. A new constructive phase in their defenses, however, will only have taken place from the confirmation of this title by King Dinis, on 27 October 1285. When the 1383-85 Portuguese succession crisis, Numão sided by Beatriz, along with the neighboring villages and castles of Penedono, Pinhel, Sabugal, Castelo Rodrigo and Trancoso. Under the short reign of D. Duarte was established here one of couto homiziados, which seems to indicate some difficulty with its settlement. The village received Foral New King Manuel I on 25 August 1512. At the time it was Commendation of the Order of Christ. The Register of Population of the Kingdom in 1527, shows that Numão village had 15 fires, and 41 more in their surroundings. With the extinction of family Coutinhos for lack of descendants, the town and its castle had their aggravated decay process: two centuries later the village was changed-to a new location at the foot of the hill. Frei Joaquim de Santa Rosa de Viterbo refers, in 1798-1799, the castle was practically ruined and that the door "which is to the West" was in one epigraphic inscription, who transcribed: "Incepit Tvrrem in was MCCXXVII". The Institute for the Management of Architectural and Archaeological Heritage classified it as a National Monument by decree published on June 23, 1910. The government intervened in the second half of the 1940s by proceeding with works of consolidation and cleaning, rebuilding walls, desentulhamento the tank and recovery the donjon. New works campaigns took place in 1973-1974, due to the collapse of a section north of the walls, and in 1984. In the early twenty-first century, the municipality did install stage lighting.
