A prime example of Manueline architecture in Lisbon churches, Mosteiro dos Jeronimos was built on the orders of Dom Manuel I to commemorate the Portuguese discoveries. Monks of the Order of St Jerome were given the spiritual responsibility of comforting and giving guidance to sailors. \r\n \r\nThe tomb of Vasco da Gama lies inside a 25m baroque vault opposite that of poet Louis de Camões. Work on the impressive structure began in 1502, following a design by architect Diogo de Boitaca, and was not completed until towards the end of the 16th century. \r\n \r\nThe sculptural façade features a hierarchical display of saints, topped by patron saint St Mary of Bethlehem (Belém). The tranquil cloisters, designed by Boytac and completed by João de Castilho, are frequently used for theatre performances and concerts. Admission prices apply to the monastery and cloisters, although entry to the church is free.
