Torre de Belém Tavel Guide
Composed of a bastion, Belém Tower or or the Tower of St Vincent is a fortified tower located in the civil parish of Santa Maria de Belém in the municipality of Lisbon. Along with the nearby Jerónimos Monastery, it is a UNESCO World Heritage Site because of the significant role it played in the Portuguese maritime discoveries. Commissioned by King John II, the tower was to be part of a defense system at the mouth of the Tagus river and a ceremonial gateway to Lisbon. Built in the early 16th century, the tower is a prominent example of the Portuguese Manueline style. It has incorrectly been stated that the tower was built in the middle of the Tagus and now sits near the shore because the river was redirected after the 1755 Lisbon earthquake.
