The original, and by far the most extensive, excavations at La Ferrassie were conducted by Capitan and Peyrony in the early part of the 20th century. They were followed, from 1968 to 1973, by more limited excavations by Delporte which focused almost exclusively on the eastern, interior part of the site. New research by the present team started in 2010 in the extreme western area of the site (actually situated outside of the original fenced area), which is immediately adjacent to the locations where the La Ferrassie 1 and 2 Neandertal skeletons were found.
