By the time the Spanish arrived, a 40m-high double pyramid towered above this spot, with steep twin stairways climbing to shrines of the two gods.
The entrance to the temple site and museum is east of the cathedral, across the hectic Plaza del Templo Mayor , where it's possible to see much of the exterior of the Templo without entering. Authorized tour guides with Sectur ID offer their services by the entrance. Pride of place is given to the great wheel-like stone of Coyolxauhqui She of Bells on Her Cheek , best viewed from the top-floor vantage point.
