Dubrovnik. Revelin Fortress
In the period of Turkish danger theis fortress was built to the east of the city in 1462. The name Revelin derives from rivelino (ravelin), a term in military architecture which refers to work built opposite the city gate in order to afford better protection from enemy attack. It took 11 years to build it, and during that time all other construction work in the city had stopped in order to finish this fortress as soon as possible. The construction work was executed so perfectly so that the devastating earthquake of 1667 did not damage Revelin.
