Historian and writer Dan Cruickshank celebrates architecture as a creative force as he explores the world's greatest cities, buildings and monuments. Since building began, architects have tried to build the future, create fantasy worlds, and even change humanity through new inventions. Dan travels to Yemen to reveal an ancient city of skyscrapers made of mud and explores the Eastern State Penitentiary in Philadelphia, where society dreamt of reforming criminals into decent men.

丹访问了世界最古老的摩天大楼城市也门，在多米尼加共和国城市圣多明戈人们如何抵御西班牙入侵的。在喜马拉雅山下的不丹国家纪念碑和费城东方州立监狱。
