Its architecture displays various elements of the Crusades, Religio Romana, Manueline and Renaissance styles, most notably the impressive keep and turret, known as the Charola. Visiting the Convento de Cristo is an unforgettable experience, giving insight into the fascinating and tumultuous past of Portugal and the power of the Christian Knights.
