The Ryugyong hotel, Pyongyang, North Korea has always been interesting to me. Just the menacing form against the skyline of Pyongyang is enough to take note. The Ryugyong hotel, in Pyongyang is 105 stories of asperation and overambition. Construction originally started in 1987 but due to the dire economic situation in 1992, construction halted. This was in time with the fall of the soviet union and North Korea's loss of its chief financial supply. It stood a naked concrete shell for fifteen years rotting. It was often removed from photographs by city official, and was not included in maps. Construction did resume in April 2008 by a contractor from Egypt. Plans have this building completed in 2012.
Note the 5 (5!) revolving restaurants on the top!!!
