Whoa, this is the first time I've ever seen this video. It shows the Costa Concordia wreck at a dock after it was raised and moved in 2014. The person filming this video snuck onto the ship to film the inside. As expected, there's a lot of damage to the ship (not surprising since it sat in shallow salt water for over a year) and a lot of missing items as the ship was partially dismantled before being towed a short distance away to port.
Pretty interesting exploration video I think. Definitely stands out from among the countless factories and abandoned buildings. If anything, it sort of reminds me of the abandoned McDonald's barge in Canada.
