The largest settlement in Svalbard, Longyearbyen, is built on a permafrost plateau and experiences total darkness for nearly three months. The community adapts with light therapy lamps and a vibrant nightlife to combat the psychological effects of the polar night.
The largest scientific community in Antarctica experiences continuous darkness for several months during the winter. Research operations continue under artificial light, highlighting human resilience in one of the most isolated and dark environments on Earth.
Situated in the far northeast of Norway, Vardø experiences one of the longest polar nights in Europe. The town is known for its dramatic landscape and the profound darkness that envelops the region, offering a stark contrast to the summer midnight sun.
A scientific research settlement on Svalbard, Ny-Ålesund is one of the northernmost permanently inhabited places. It endures several months of darkness, relying on extensive scientific infrastructure and artificial lighting to sustain operations in the harsh polar environment.
Located on Ellesmere Island, Eureka holds the record for the coldest temperature in Canada and experiences darkness for over five months. The remote research station operates in near-total blackness during winter, making it one of the darkest inhabited places on Earth.
The northernmost permanently inhabited place in the world, Alert experiences darkness for more than six months each year. The military outpost and weather station rely on artificial light, as the sun remains below the horizon for the majority of the winter.
Located in southern Patagonia, Punta Arenas experiences long, dark winters with very short days. While not in the polar night, the low sun angle and frequent cloud cover contribute to a gloomy, dimly lit atmosphere during the winter months.

Located in Utqiagvik, this research facility studies the impacts of climate change on the Arctic environment. Researchers work through the long polar night, utilizing advanced technology and artificial lighting to conduct critical scientific experiments in the dark.
While not subject to polar night, Zermatt's high altitude and surrounding mountain peaks create areas of permanent shadow. The Matterhorn and other peaks cast long shadows that can leave parts of the valley in darkness even during daylight hours, creating a unique microclimate of shade.
Located in the Danakil Depression, Dallol is one of the hottest and driest places on Earth. While not dark due to latitude, its deep salt flats and mineral formations can create visual illusions of darkness, and extreme heat can distort light, creating a surreal, shadow-like atmosphere.
Deep cave systems like Son Doong in Vietnam and Movile in Romania are entirely cut off from sunlight. These subterranean environments are perpetually dark, hosting unique ecosystems that have evolved in total absence of light, relying on chemosynthesis rather than photosynthesis.
