- On the side of the road that links the towns of Constantine and Betna, in the township of El-Boumia Daira d’El-Maadher,

- every traveler can catch the glimpse of a great building that the first Numidians wished to set in the middle of the old road that linked the South of the Numidian kingdom to the north,

- along the High Atlas range and the wide meadows of Bumia. The searchers ignore the reasons for that,

- as well as what was buried in the tomb, to which social class he belonged to and what the secret of the name of the tomb is.

- Some say that Medgassen comes from the Berber word Imedrassen Thamdroust, in the chaui language Thamdhroust Imdhrassar, which means the stairs.

- The second option is that it comes from a Madderssen grandfather’s name, that means the glorious one and that gives the raison d’être to 2 things, 2 people or 2 tribes.

- The architectural shape of the Madgassen tomb has Numidian contents suggesting the existence of relationships between both the Numidian and the Greek civilizations,

- founded by a very ancient civilization, more ancient than the pharaohs.

- This civilization that dates back to 611 B.C. is the witness of the crossing of the Greeks and the Amazighs in its favorable and close civilization.

- It came after Sheshonq Ist’s Egyptian civilization. Then another civilization was founded in Libya; it is that of today.

- The sanctuary of Madgassen, a site of pilgrimage for the Numidians and where they used to gather every year,

- must be deeply searched to reveal its secrets, such as number 7 that can be spotted several times in the building,

- researches that will remove the mask of historical components that remain hidden.
