Everyone out to get you? Build a city underground like Enver Hoxha. Tirana

You could argue that the Enver Hoxha, the communist leader of Albania from 1941 to his death in 1985 was a little paranoid. He believed everyone was out to get him, which led to an extreme bunker mentality. This not only manifested itself in the 170,000 plus small concrete bunkers built across Albania but in his preparations for governing Albania in the event of an attack.

Wolf's Lair. Visiting Hitler's secret headquarters in the far north of Poland.

In the forests of northern Poland, just 10km from the Russian border, lie the remains of Hitler's secret war headquarters.

The ancient caves of Uplistsikhe

15km north of Gori in central Georgia lies the cave dwellings of Uplistsikhe. Situated high above the River Mtkvari, and surrounded by rich agricultural lands, it is one of the oldest settlements in Georgia, with archaeological findings showing that there have been signs of habitation for over 3,000 years, since the Bronze Age.

Hiding from the Mongols inside a mountain. Vardzia

In the twelfth century, the Mongol hordes were threatening to overrun Georgia, as they had already done to so many other countries. The warrior Queen Tamar ordered the construction of a hidden city, to provide safety and as a place of resistance should the Mongols succeed in their invasion, and the secret city of Vardzia was born.
