As you will see Valparaíso offer a divers landscapes of forests, lakes, valleys and even waterfalls, but this forests also hide part of the history of the city when about 100 year ago in the middle of the golden time and the prolific development of Valparaíso they decide to build the second hydroelectric plant and the first one in Chile for a public purposes to give electricity to the city but mostly to the tram public transport. A that time was one of the biggest and most important engineering project in Chile, but in 1995 the plant was close due to the cost of its operation, and the owners decided to abandon the place. The ruins of the whole complex remained there but now the whole land belong to a real estate company, what have been bringing some problems to this area because since couple of year ago they have been building new neighborhoods and destroying the forest around without taking care about the natural and history heritage of this zone of Valparaíso. That is why this tour goes through the history, innovation, develop, nature and current situation of “Placilla city”.
