The village of Vathia dates back to the 16th century. It's such a remote area that it has never had a large population, however the population has fluctuated wildly. They say that at one point in the 1800's there may have been as many as 400 people living in the area, and even as recently as 2001 there were almost 200.
However now, there might be 20 living in the area full time, if that. And even fewer in the actual village itself.
