Poloniny Dark-Sky Park
Prešov Region, Slovakia · built 2010
Poloniny Dark-Sky Park (Slovak: Park tmavej oblohy Poloniny) is the first dark sky park in Slovakia. It became the 20th dark sky park in the world. Natural total night darkness, which would be unaffected by artificial light, no longer exists in Slovakia because of light pollution, but there are still places where this influence is minimal. Such a place is the Poloniny National Park, which is in terms of light pollution the darkest area in Slovakia. Therefore, the Slovak Union of Astronomers started an initiative to establish a dark sky park there.
