Today there will be two abandoned object:
Dead City (Krakow Italy) and an abandoned landfill laboratory ultra-high voltage (St. Petersburg Russia)
Let's start with the first:
By 1891, the population of Krakow was 2,000. Heavy agricultural conditions led to the food crisis, which resulted in about 1,300 people left the city and moved to North America in the period from 1892 to 1922. By the agrarian crisis joined by frequent earthquakes and landslides. As a result, in 1963 the remaining 1,300 inhabitants were relocated to a nearby valley, called the Cave of Krakow and Krakow itself is well worth it in the same place, only now completely empty.
