Underwater Sculpture Park
The Molinere Underwater Sculpture Park can be found in Grenada in the Caribbean Sea, and for just $2 you can dive down to visit the strange underwater attraction. Designed by Jason deCarires Taylor, these sculptures have been here since 2006. While the attraction is not deserted, it does still give an eerie feel because of the underwater figures.
Constanta Casino
Originally built in 1910, Constanta Casino in Romania cost $8 million to build with all of the luxurious fixtures available at the time. By 1990, it was too expensive to keep open and it shut down. While there have been pushes to renovate it, any plans have since been stalled.
