2D-ERT prospection in the Plaza of Santo Domingo, Mexico city

What is it about?

The objectives of this investigation were to establish the position of the northwest corner of the ancient Mexica wall and to determine whether the Plaza became a public square during pre-Hispanic or colonial times, taking into account the contradictions of the historical sources. For this purpose, we implemented three 80-m-long ERT profiles in the plaza and one on the eastern side of the Church of Santo Domingo de Guzmán. A Wenner-Schulmberger array was designed for the data acquisition. The results could support the hypothesis that the Plaza of Santo Domingo was designed and constructed as an open public area in colonial times, since the observations in the electric profiles beneath the square could reveal the presence of a pre-Hispanic structure. This structure could be part of the wall that surrounded the Mexica ceremonial compound.

Why is it important?

The exact location of the NW corner of the pre-hispanic wall was not certain. With this study we were able to find it.
