“The Margaritius’s waterfall complex is one of the thousands of examples of hydrocyan facilities created in Greece during the pre-industrial period. The two mills, which are made in a row and an altitude difference between them to take advantage of the most possible amount of water available, were fed from at least two sources that existed in the adjacent hills. These are simply one-room buildings, housed with a keraposse, having an overground space for grinding of cereals and an arched semi-basement, where the horizontal impeller moving the grinding mechanism was located. The water reached the upper mineral mill with 25 meters long. And dried down to the drive mechanism. Naturally, naturally flooded under the arched opening of the western wall of the mill, to the lower and best preserved hydraulic, approximately 60 m long and 3.80 m high along the compact body of the latter, six arcs are formed They are visible five – of which the three westerners were closely closed with dry stone. On the upper surface, the aqueduct – “Myrlalakos” is formed. The ND endowment of hydraulic is externally formed, so that miller has access to water flow control while internally there is a sloping bundle that drank water with pressure to the underground mill chamber to rotate the milling mechanism. Although there are no safe chronological indications for the construction of the complex, two Ottoman coins detected in the foundation of the lower hydraulus allow us to assume that the two mills were constructed in the 19th century, while the senior of them survives – at its final phase as diesel – up to the middle of the 20th century. ” It is an outdoor area, constantly open. The water mills are located on EO. Igoumenitsa – Preveza at the height of Margariti, about 25 km from Igoumenitsa.
