The great powers in Europe had already fought each other before the First World War. A relic of this period is Fort Vrmac at the coast of Montenegro.
The biggest attraction in the ukrainian city of Odessa is not located on the surface, but below the ground. Welcome to the largest catacomb network in the world!
The last stop on my trip through Belarus was the border city of Brest. Only the Brest Fortress has survived the Second World War, but not just the giant memorial complex is worth a visit! 🙂
