The Jerónimos Monastery was originally constructed in the early 16th century on the orders of King Manuel I of Portugal as a monastery for Hieronymite monks. It was built in the Manueline style of architecture, which featured ornate maritime motifs. The monastery served as an important religious and royal site for centuries, housing the tombs of explorers like Vasco da Gama and poets like Luís de Camões. It underwent restoration in the 19th century after falling into disrepair and now operates as a museum.
