The Carmo Convent was founded in the 13th century, during the reign of Afonso III of Portugal, specifically in 1251.
The convent showcases Alentejo Gothic architecture with three naves, each divided into six sections. Over the centuries, it underwent some Manueline and Renaissance modifications. A highlight is the Manueline vaulted ceiling, where the Cross of Christ can be seen. Both the façade and the main portal, as well as the cloister, display the symbolism of the Order of Malta.
The Carmo Convent was the headquarters of the Carmelite Order in Portugal and the first convent of this order in the Iberian Peninsula. It was intended to host chaplains of the Knights of St. John of Jerusalem returning from the Holy Land.
Since 1944, the convent has been classified as a Property of Public Interest.
