The urban exploration movement continues to reveal more ghostly abandoned structures from every country and era... for example, bloggers for the site English Russia recently conducted a tour of long-abandoned summer camps on the bank of Russia's Desna River, and found some pretty unsettling images on their journey.
The signs, landmarks and artwork reveal that these camps were summer vacation spots for “Little Octobrists,” special groups for kids born in the early Soviet era.
The photos reveal housing, dining halls, auditoriums and playgrounds, all more or less intact, but with an air of ominous mystery.
The creepiest finds include some seriously surreal artwork on the playground.
These were obviously intended to be fun and inspiring, but the passage of time has given them a more menacing look.
Also we're not sure what's up with this weird, tiny cabin on stilts... the purpose of which remains unknown.
You can see the complete gallery at English Russia, with translations of many of the signs. (Thanks to BuzzFeed for spotting this one.)
