St.Jacobs Bastion is a part of riverside fortifications of the Belgrade fortress commisioned by the Ottoman sultan Mustapha II at the end of the 17.century. At first, it was called Sultan Mustaphas Tabia, but after the fortress was captured by the Austro-Hungarian, it was renamed as St.Jacobs Bastion (in serbian Bastion Svetog Jakova). It is also the finishing point of the 960km long Sava river Bike Route, which goes through 4 countries.
Today this bastion is a part of riverside hiking/cycling path and offers a beatiful view on the confluence of Danube and Sava rivers. The view is especially nice in the evenings when you can watch the sunset by the riverside. Near this bastion you can also visit Nebojsa tower (Kula Nebojsa) which dates back to the 15th century.
