In 1141, D. Afonso Henriques sells the Carta de Couto to the abbot of the Monastery for 150 Morabitinos. In 1560, it was annexed to the Convent of S. Domingos de Lisboa, by decision of Pope Pius IV. In the eighteenth century, several buildings were constructed that still make this architectural ensemble remarkable: the granaries and the cellar, the octagonal chapel of Nosso Sr. do Bom Despacho and, probably, the Fontanário. At the beginning of the century. XIX, the Monastery was sold at public auction, being held by the Baron of Ancede.
