Lake Ziros is an important and stunning natural attraction, which is relatively unknown to the public because it is not shown on tourist maps with a scale below 1:300,000. The buildings of Ziropolis were designed by Austrian architects in 1955. The lake is approximately 1000 m long and 500 m wide and has an elliptical shape. It has a depth of over 25 m at its deepest point. Until 1965, when it was almost destroyed by an earthquake, Ziropolis was an important educational, cultural and economic centre in the region. http://www.visit-preveza.com/el/ziros
