Abandoned Whittingham Hospital Escape

Roy had gone out to take some pictures of the ruins of the Whittingham Hospital as he wanted to publish a related article on his blog along with some real pictures which would bring a bit more authenticity ad attraction to his article. He did manage to get some awesome shots from outside but he wanted some from inside as well and so he walked inside. He did go around for a while and forgot that he had left the entrance way back. When he realized that it was time for him to go back home, he just could not spot the exit. He got trapped. After a long struggle, he succeeded to get out from there. Can you get out of the same place if you are trapped like him?
