A Tree of Souls from James Cameron's Avatar.
The Tree of Souls (Na'vi name: Vitraya Ramunong) is a giant willow-like tree that is said to be the closest connection to Eywa on Pandora. As pointed out by Miles Quaritch, the tree is a point of extreme spiritual significance to the Na'vi, more so than any other point on Pandora. As of 2154, the site has been spiritually significant for at least 3,000 years.
