The city is unlike anywhere else thanks to its vertically sprawling cityscape where buildings cling to cliffs.
Chongqing, China, a megacity of 32 million, is the world's largest city with few tourists. Known as a "city in three dimensions" due to its mountainous terrain and vertical cityscape, it features unique infrastructure like metro lines running through buildings, elevated roads, and urban escalators. Despite its size and rapid development, Chongqing remains relatively unknown to international tourists.
