This archeological site is located 7 km northwest of Llerena, on a large area of over 330 ha, in a sector where the three municipal districts of Casas de la Reina, Llerena and Higuera meet. The site corresponds to a modern trifinium, although the main nucleus of the structures is in the municipal district of Casas de la Reina. The archeological surveys carried out could not detect any traces of use of the land after Roman times.

This peneplain, with gentle relief and sweeping panoramic views, constitutes an extension of the last northern foothills of the Sierra Morena mountain range. This area benefits from permanent water supply points, extensive meadows, pasture areas and a residual holm oak forest. In addition, the abundant surface stone constitutes a practical and inexhaustible construction material, which has turned it into an island surrounded by farmland.

Literary sources (Apian, Iberia 67-71), point out the key role played by this region in Baeturia during the Lusitanian Wars. Moreover, it is important to highlight the relative closeness of Arsa and Regina, two of the six oppida non ignobilia of the Baeturia Turdulorum quoted by Pliny ( Nat. Hist. III, 3, 14).
