Mys Aniva lighthouse, Sakhalin Island, Russia

Aniva is a coastal town on Russia's Sakhalin Island, near Japan. The Mys Aniva lighthouse sits on the rocky coastline, abandoned and worn down.

The lighthouse was built by Japanese engineers in 1939, and was used by both Japanese and Russian militaries over the years.

The site is popular today among urban explorers, some of whom have found belongings of people who once lived in the lighthouse.
