Abandoned Okpo Land Amusement Park in South Korea closed in 1999 after the Duck themed ride capsized and threw a young girl out of the compartment and down to the pavement below. She died and the park closed that same day.
THESE are the terrifying tunnels! 5 miles of these underground tunnels connect all the building on the site. I am CONVINCED there are ghosts in these tunnels based on the hospitals history and my own experiences!
