Linh Đàm is a neighborhood located in Hoàng Mai district, Hanoi. With a population of about 80,000 people, Linh Đàm is among the most densely populated neighborhoods in Vietnam. First settled in around the early 1600s, the area was mostly a swamp and sparsely-populated area until the early 1990s, when it was planned to relieve overpopulation in the urban core of Hanoi. The neighborhood is characterized by tall buildings and the Linh Đàm lake serving the community.
