Feste Kaiser Alexander, Prussian fortress in Koblenz, Germany.
The fortress extends across 500 meters on each side, featuring thick walls, bastions, and a central reduit designed for military defense.
Construction of the fortress began in 1816 and finished in 1824, named after Russian Tsar Alexander I during the period of Prussian fortification expansion.
The Lion Gate entrance displays classical architecture with cast iron griffin reliefs and stands as the remaining preserved section of the original structure.
Visitors can access the fortress grounds and climb the spiral staircase inside the Lion Gate to reach the roof observation point.
The fortress contained an underground tunnel connecting it to Fort Großfürst Konstantin, completed in 1831 for strategic military operations.
