A Native American tribe has officially reclaimed a part of their ancestral land in California’s scenic Big Sur coast after ceding control more than 250 years ago to Spanish colonial settlements, courtesy of a conservancy group.

The Esselen Tribe, which is one of the state’s least-known tribes, has now taken control of over 1,199 acres which is located about 5 miles inland of the ocean in what is said to be a $4.5 million deal with the state and the Western Rivers Conservancy, reports CNN. The landmark move is the first-ever restoration effort for the tribe which had reportedly lost 90 percent of its 1,000 member group due to diseases in the early 1800s.
