Sancho I of Portugal
This bastion was conquered on 3 June 1189, by the forces of King Sancho I of Portugal, with help from Crusader forces. It was retaken two years, and definitively reconquered in 1250. Rebuilt by King Denis in 1300, it served for 500 years the coastal defences against attacks by pirates and privateers until it was destroyed in 1755 by the tsunami and earthquake that devastated Lisbon.
