Now their underwater hotel is near to its opening date â€“ finally, as its opening day is always delayed. This hotel, named as Hydropolis Sea Resort, will be open to the public soon. Like their other famous structures, this luxurious underground hotel looks more like a giant sea monster at a distance than an underground building.
This underground hotel is said to be worth Â£300m. Interestingly, unlike other hotels, this building is protected by a missile defense system.
