Ko Panyi: Thailand's Floating Village  

Aerial view of Ko Panyi, fishing village in Phang Nga Province, Thailand. Photo credit: roadlessandy/instagram In a sheltered bay in southern Thailand, under the shadow of an immense, almost vertical limestone cliff, hundreds of huts, shacks, restaurants and houses cluster together to form the village of Ko Panyi. The sea here is shallow and calm allowing fishermen to build houses raised safely above the water level on stilts. More than 300 families and nearly 1,500 people live permanently on K

Transnistria, The Country That Doesn't Exist  

After the collapse of the Soviet Union in 1990, a thin sliver of land on Moldova's eastern border with Ukraine broke apart from its parent country and declared independence from Moldova. A four-month war followed and some 700 casualties later, a ceasefire was signed. Since then, Moldova has stayed out of Transnistria's business but still refuses to recognize it as an independent state. In fact, no other nation does. Yet, Transnistria acts as an independent country, with its own government, ...

It ended when Tokugawa Ieyasu came into power and established the Tokugawa shogunate and unified all of Japan under a feudal system.

Just off the northwest coast of Germany, in the North Frisian Wadden Sea, are a series of ten extremely low-lying islets known as Halligen or Hallig islands. The Hallig Islands rise only a few feet above sea level, so every winter when the tidal flats of the Wadden Sea gets inundated, the islands go under water. In the Middle Ages, there were a great number of Halligen, but with rising sea level several of these uninhabited islets on the Wadden Sea have vanished beneath the waves for ever. Barel
