Rongelap Island is not a city but rather an atoll located in the Pacific Ocean. It is part of the Ralik Chain of the Marshall Islands. The island is relatively small, only about 2.5 square miles in size, and it has a population of around 90 people. The main settlement on Rongelap Island is called Rongelap Village. However, as it is not classified as a city, it does not have the same level of infrastructure and amenities as a typical urban area. The island is mainly known for its pristine beaches, coral reefs, and historical significance as a nuclear testing site during the mid-20th century.
