01. Ryugyong Hotel
This hotel was meant to be opened in 1989 but was never completed. If completed at that time, it would have been the seventh largest skyscraper and the tallest hotel in the world. The hotel was supposed to consist of 3,000 rooms, seven revolving restaurants, casinos, nightclubs, and lounges. This hotel is yet to host a guest but the construction may soon resume on the 105 story building. The Ryugyong Hotel would be one of the most amazing places to visit if it ever sees a completion date.
