Archeological investigations of the site were published in 1927, 1951, and 1999.[1] The first one, by Henri Basset and Henri Terrasse, was started in 1923 and the results were published in 1927 (no excavations were carried out). Since no masonry was used and the buildings were all executed in a simple and unadorned manner, they concluded that the fortress was quickly constructed, though the surface area indicated that a large garrison must have been stationed here.[2] After the discovery of the fort at Koutoubia, a second study at Tasghîmût was begun in 1949, led by Charles Allain and Jacques Meunié. First they studied the terrain, and 1951 they began excavating the most important buildings: the gates, the western bastion, and parts of the kasbah.
