The Monastery of Jerónimo on the Belem coast is one of the many architectural jewels of Portugal. It is most famous as a place to pray for seafarers, prior to setting out on a voyage. This tradition was begun before the current construction was built when Vasco de Gama, no less, went to pray prior to setting off for the Orient.
Construction of the current temple began in 1501 and took a century to complete, with King Manuel using the tax on imports from Portugals newly formed global reach to fund the project. With business being so good and the expansion of Portugals reach, he could afford to furnish the monastery in a rather lavish way. Including the works of several renaissance artists adorning the walls and columns.
