In the first decades of the 20th century, Manuel Gamio found part of the southwest corner of the temple and his finds were put on public display. However, the discovery did not generate great public interest in excavating further, because the zone was an upper-class residential area. In 1933, Emilio Cuevas found part of a staircase and beam. In 1948, Hugo Moedano and Elma Estrada Balmori excavated a platform containing serpent heads and offerings. In 1966, Eduardo Contreras and Jorge Angula excavated a chest containing offerings, which had first been explored by Gamio.
