The Vatican City State is a sovereign city-state, whose area is a 44 hectare walled enclave west of the Tiber River, within the city of Rome. With a population of about 850, it is the smallest independent state in the world by both area and population. The independent city-state was established in 1929 by King Victor Emanuelle III of Italy. Vatican City is an ecclesiastical state ruled by the Bishop of Rome -- the Pope. The image was acquired July 4, 2010, covers an area of 10 by 13 km, and is located at 41.9 north, 12.5 east.

Italy’s capital city shows a distinctive patchwork of lights and darker areas when seen from the International Space Station at night. Unlike England’s capital city, Rome’s A90 ring road, the “Grande Raccordo Anulare”, is not so visible due to different motorway lighting. No single point of interest strikes out from the patchwork of roads, parks and green areas.
Rome was famously founded along the Tiber river, seen here winding its way downwards to the bottom of the image, but even the Tiber river gets lost in the sea of light at the center of Rome. The dark patches are parks, ancient ruins and green areas without street lighting. To the bottom right of this picture is the hilly area and regional park of Decima-Malafede where humans have not settled. Instead Rome has expanded over the years in other directions. At the top of this picture, newer, sub-urban settlements are characterized by the straight streets.
ESA’s center for Earth Observation at the ESRIN facility near Frascati can be seen to the right of this picture, above the blackness of Albano lake.
Clouds covered parts of Rome and caused the blurry areas at the bottom half of this picture taken 12 December 2013 by an Expedition 38 astronaut.
