The construction of Castelo de Tomar started in 1160, at the hands of the Templars, as part of a line of defense against Muslim attacks. This objective was to be proved in 1190, with an attack by the forces of the emir of Morocco, in which Tomar not only resisted the siege but inflicted heavy casualties on them, passing one of the castle doors to be called the Blood Gate. With the extinction of the order in 1312, King D. Dinis handed Tomar over to the Order of Christ, of which Infante D. Henrique, who would have resided in this castle, would become governor. From 1495, during the reign of D. Manuel I, several works were carried out within the castle grounds, such as the expansion of the Convento de Cristo and Paços da Rainha, creating one of the most beautiful Portuguese architectural ensembles, in a harmonious meeting of several architectural styles.
