The World's Most Crowded Santa Cruz del Islote

Santa Cruz del Islote is the world's most densely populated artificial island, where over 800 people live on an area of only 0.01 km². This small piece of land, measuring 130×190 meters, is located in the Caribbean Sea off the coast of Colombia. There are only four streets and about a hundred houses, no authorities and no police, but there are a few shops and a school, and electricity is generated by solar panels.
