North Korea 2015 : 27 / 164
The Ryugyong Hotel was begun in 1987 but construction was halted in 1992 as North Korea entered the 'Arduous March', a period of severe economic crisis. Construction resumed in 2008 and the exterior was completed in 2011. Openings were scheduled in 2012 and 2013, but it never happened. At the time of our visit in 2015 it remained unopened.
