Discovered in the 1990s, this 400,000-year-old Homo heidelbergensis structure in France is believed to be a primitive hut or shelter made from wooden posts and branches. The structure is thought to have been built by Homo heidelbergensis. The shelter is estimated to be around 4-5 meters (13-16 feet) wide and 6-7 meters (20-23 feet) long. It’s believed to have been constructed using a simple framework of wooden posts, with branches and leaves used to create a roof and walls. While the above image is a minimalist artist representation, the following is more likely what their camp looked like.
