Under the present leader, Kim Jong Un, construction has ramped up apace-"Let us turn the whole country into a socialist fairyland," declares one of his official patriotic slogans. He is rapidly transforming Pyongyang into a playground, conjuring a flimsy fantasy of prosperity and using architecture as a powerful anesthetic, numbing the population from the stark reality of his authoritarian regime.

Guardian journalist and photographer Oliver Wainwright takes us on an eye-opening tour behind closed doors in the most secretive country in the world, revealing that past the grand stone façades lie lavish wonder-worlds of marble and mosaic, coffered ceilings, and crystal chandeliers, along with new interiors in dazzling color palettes. Discover the palatial reading rooms of the Grand People's Study House, and peer inside the locker rooms of the recently renovated Rungrado May Day Stadium, ready to host a FIFA World Cup that will never come.

This collection features about 200 photographs with insightful captions, as well as an introductory essay where Wainwright charts the history and development of Pyongyang, explaining how the architecture and interiors embody the national "Juche" ideology and questioning what the future holds for the architectural ambitions of this enigmatic country.
