The Convent of Christ is a former Roman Catholic convent in Tomar, Portugal. It was originally a 12th-century Templar stronghold but when the order was dissolved in the 14th century the Portuguese branch was turned into the Knights of the Order of Christ, which later supported Portugal's 15th century maritime discoveries. The convent and castle complex are an important historic and cultural monument, and were listed as a UNESCO World Heritage site in 1983.
