Mosteiro dos Jerónimos
This sixteenth century monastery is the wonder that can not miss a visit to Lisbon . It is a journey to the Age of Discovery when the spices of the East paid for the great monument of architecture. It was this historical and architectural significance that led to the recognition of the monastery as a World Heritage Site. Treasures from all over the world arrived in Lisbon after Vasco da Gama have opened the sea route to India , and the tomb of discoverer was placed at the entrance of the church. Maritime motifs are carved throughout the interior (unique in the world) , from corals to strings, which can also be admired in the magnificent cloister . This cloister is often used as a stage for special events, such as the signing of the Treaty of Lisbon in 2007 , joining the leaders of EU members .
