No wonder this site has been declared a UNESCO World Heritage Site and one of Portugal's Seven Wonders. Convento de Cristo is a religious and Roman Catholic building, originally a Templar stronghold built in the 12th century. After the Order of the Knights Templar was dissolved in the 14th century, the Portuguese branch of the order was turned into the Knights of the Order of Christ, which supported Portugal's maritime discoveries of the 15th century.
The exterior and interior architecture of the Convent is totally impressive and the Round Church is an absolute jewel. The castle and Convent of Christ have examples of Romanesque, Gothic, Manueline and Renaissance architectural styles.
The admission fee is 6 euros, but if you intend to visit the rest of the UNESCO sites nearby, which is highly recommended, it’s worth it if you purchase the combined ticket of 15 euros that allows entrance to these 3 sites (Alcobaca Monastery, Batalha Monastery and Convent of Christ). At Alcobaca’s ticket booth they accept credit card payments.
