Where is the darkest city in world?

The darkest city in the world is Longyearbyen, located on the Norwegian island of Spitsbergen, in the Svalbard archipelago. It is the world's northernmost settlement with a permanent population of over 1,000 people. Due to its location above the Arctic Circle, Longyearbyen experiences periods of polar night, where the sun does not rise for several weeks during the winter months, resulting in almost continuous darkness.
