Poenari Castle, also known as Poenari Citadel or Fortress, is a ruined castle in Romania, on the cliffs of the mountains (at a height of 860 meters), notable for its connection to Vlad the Impaler. The construction of this castle began in the 13th century, under the rule of the Black King. In the decades that followed, the name and the residents changed a few times but eventually the castle was abandoned and left in ruins. It was Vlad the Impaler that brought it back to life

The ancient Greek Titan guards this massive dam holding a lightning bolt to symbolize electricity. The Vidraru arch dam on the bank of the Argeş River in Romania is an engineering jewel. Built in 1966 to create hydroelectricity, it was the fifth largest dam in Europe at the time. It required 42 kilometers of tunnels, over a million hard rocks extracted from underground and nearly a million cubic meters of concrete to build, plus the loss of about 80 builders’ lives.
