The Palenque 3D Archaeological Atlas

Arianna Campiani, Rodrigo Liendo Stuardo and Nicola Lercari, along with other colleagues have been collaborating with Scott McAvoy on developing a web-based Archaeological Atlas of Palenque. The idea is to gather in an online platform, easy to interact with, the digital recording of our excavations and the 3D documentation of the Palenque site core.

Specifically, by following the link associated with the image below, you will be redirected to the 3D Atlas website.

Several excavations and burial models are visible within this web-interface, mainly corresponding to the 2018 fieldwork season, where Lisa Johnson excavated J7 building in Group IV. You will be able to surf into the different layers of this excavation (operación 400). As well, you will be able to see a burial excavation (operación 401) with the photogrammetry of a vessel retrieved in a crypt, restored and digitally “re-contextualized” in it (models by MayaLab collaborator Mirko de Tomassi).

The results of this work are described in a journal article recently published in Digital Application in Archaeology and Cultural Heritage.

Documenting our excavations in 3D

Since several years we have been using photogrammetry to integrate the documentation of our excavations. Beside drawing and sketching our excavation layers, this technique allows us to register the process in 3D.

Here you can see the beginning of Operation 471, after removing the humus, we had this collapse of a platform building, with no walls exposed.

Prior to the removal of the collapse, also the side of building J37 appeared “messy”. But the intact walls were just underneath the fallen stone blocks. Here you can appreciate how it looks like in Operation 472A!

We are also investigating the front of J37 building, to understand if this mound was actually enclosing a single building or several constructions..In fact, it often happens that the collapse of several contiguous constructions generate a one big mound. Few of the findings of trench 472B have been described in our last post.

While Operations 472A, 472 B and 471 are located in the architectural compound south-east of Group IV, other buildings are being excavated north-east of Group IV (see our recent post).

Operation 473 is exploring a building close to the Takin Ha stream, which runs within our neighborhood. Even with the blue and red colors generated by the tarps we put to create shade on the excavation, it is possible to appreciate the steps leading to the room of the building, as well as the back wall.

Of notice, a flipped metate was placed at the foot of the building (in the blue shaded side of the model)! We found another flipped metate at the base of the pyramid just next to this building, where Dee and Mo started excavating.

Week 2 of the 2023 Field Season

It was a busy week in excavations! Following days of removing humus and collapse, the architecture began to emerge! We are focusing on two different structural groups. As mapped, it was clear they were different in terms of structure size, form and orientation. Mo and Dee have been working in one group, excavating a pyramidal shape structure and a long, linear structure that abuts it. This small group appears to have been surrounded by water, making it a rather interesting group. Large concentrations of manos, metates and ceramics were found in the patio area surrounding the structures.

Next to the pyramid, Sergio and Pablo have quickly found intact walls, an inner room and a solid basal platform of a long, linear structure. Arianna and Lisa have been diligently documenting the architecture with photoplans and 3D scans.

In the other group of structures, the rest of the team have been hard at work excavating structures J33 and J37. Like other residential groups, we have been finding a diverse suite of materials including ceramics, figurines, manos and metates. Interestingly, we are also finding a number of exhausted blade cores and obsidian core shaping debitage.

Next week will be another busy week!

Primeros trabajos de la temporada 2023!

Después de un largo viaje y de haber quedado atrapados en el AICM por la ceniza del Popo, el equipo del MayaLab ha logrado reunirse en Palenque para empezar la temporada 2023!

Mientras que algunos terminan las últimas compras, los otros visitan el sitio de Palenque guiados por la inarrestable MO!


Este año tenemos un equipo interdisciplinario con muchas ganas de trabajar!


También en esta temporada vamos a explorar la vecindad de Palenque cuyo centro es el Grupo IV, en donde se están realizando trabajos de excavación y consolidación.


El año pasado habíamos identificado dos conjuntos arquitectónicos dónde excavar, al este del Grupo IV. Estos se escogieron de acuerdo a una elección aleatoria basada en la forma de los edificios.

Así el equipo se dividió en dos grupos, y con la ayuda de Sergio, Pablo, Christian, Víctor y Víctor Manuel iniciamos con trazar el perímetro de las excavaciones.



En los primeros niveles ya empezamos a encontrar material como cerámica y figurillas. En general, estos hallazgos nos dan una mejor idea sobre la temporalidad de los edificios, pero también nos hablan de los usos y costrumbres de los antiguos palencanos, como por ejemplo sus divinidades, la manera de vestirse o sus peinados.


A ver qué nos espera en esta temporada en donde el calor está fuerte y la humedad más, pero la gana las supera!! Les iremos informando sobre nuestros hallazgos! Stay tuned!

Puesta en valor de estructuras en el Grupo IV de Palenque

El Instituto Nacional de Antropología e Historia (INAH) publicó en su página de twitter un video del Grupo IV de Palenque, en donde se entrevista nuestro colaborador el Dr. Rodrigo Liendo Stuardo.

Como se menciona en la nota del INAH, se están interviniendo numerosos edificios en el Grupo IV, con el objetivo de consolidarlos para poder abrir al público esta zona del área arqueológica en el segundo semestre de 2023.

Siguen las excavaciones en el Grupo IV de Palenque

El dr. Rodrigo Liendo Stuardo, fundador del MayaArchaeoLab, y director del Proyecto Regional Palenque, sigue excavando en el Grupo IV de la antigua ciudad de Palenque, como parte del Programa de Mejoramiento de Zonas Arqueológicas (Promeza), vinculado al proyecto del Tren Maya.

El Instituto Nacional de Antropología e Historia ha publicado en su página la nota “Hallazgo de miles de restos cerámicos permitirá reconstruir la vida cotidiana de la antigua ciudad maya de Palenque (chequen la nota dando click en el link), resaltando el gran número de tiestos recuperados, que sobre todo remontan al siglo VII C.E., es decir que corresponden al reinado del gobernante K’inich Janaab Pakal.

Estos restos servirán para construir un catálogo de referencia sobre la cerámica de Palenque.

Mayalab collaborators in Rome, Italy!

Last week, Dra. Arianna Campiani and the University of Rome, Sapienza hosted a series of presentations/workshop around the subject of urbanism among the Classic Period Maya. Presenters included Arianna Campiani, Nicola Lercari, Lisa Johnson, Lucas Johnson, Rodrigo Liendo Stuardo, Rosemary Joyce, Felix Kupprat, Luisa Migliorati and Josep Ligorred Perramon. What a wonderful time in Rome and very interesting presentations!

UNAM Palenque team/INAH continues to work on a Lithic Workshop and Group IV ahead of the Maya Train

Mayaarchaeolab collaborators Rodrigo Liendo Stuardo and other UNAM affiliates along with INAH archaeologists are working hard ahead of the Maya train. As the infrastructure of the park undergoes an upgrade, the archaeologists are carefully documenting and analyzing a lithic workshop with evidence of extensive production of obsidian and chert no doubt to provision the once densely occupied city. It’s central location next to the Palace is also notable. Check out the video/interviews of our friends!

PREP Team Field Season 2022 Week 2

Work has picked up in the second week and the team has moved a lot of dirt even through the afternoon showers. In JO33, we have three excavations open across the southern most structure/rooms and have cleared and detailed the northern and the southern walls running east/west. The walls are complete with no entryways or stairs so we will open additional excavations next week to look for an access point into this area of the building.

We finished the area outside of JO33, along the southern wall and came down to bedrock. It is clear this area was a large dump of household trash as there were bags and bags of ceramic sherds, lithic tools and debitage, figurines, whistles, faunal, shell, manos and metates removed from this area. The collection of figurines from this area is highly diverse. Surprisingly, there were no plaster floors detected outside of the structure (like a paved patio space) and instead, there was roughly 10 cm of a darker earth lens that was most likely an earthen floor. This level was sampled for paleoethnobotany and soil chemistry.

Meanwhile, Lisa and her team continued to excavate the summit of the structure into large cobble fill. The team has not found any interior surfaces yet, but will continue into next week. The team will also extend excavations across the large mound to clear and define the architecture to the north.

In the group of structures directly south of JO33 (and presumably a neighbor for the purposes of our neighborhood study), Arianna and her team have cleared and defined the southwest corner of the structure abutting the Motiepa. Like JO33, they have recovered a suite of materials typical of a residential group including manos and metates, figurines and pottery. Ari continues to look for the front of the structure but has so far only found collapse.

Next week promises to be another busy week as we will begin processing the artifacts from the excavations and continue defining architecture.

PREP team 2022 Field Season: week 1

Three years after the pandemic froze all travel, we were finally able to return to Palenque to continue our investigations of residential groups. But we returned to a very different Palenque. The site is swarming with construction workers sent to the site to upgrade some of its facilities ahead of the national Maya Train project. The site’s only public bathroom has already been demolished and will be cleared for the construction of a new bathroom. There are some archaeologists overseeing the work as it will impact the archaeology there, particularly the possible lithic workshop. The next major overhaul will take place in the camp. The research house and lab facilities are scheduled to be demolished as well, to be rebuilt and it’s infrastructure upgraded.

There are some tourists but the level of visitation is very low compared to prior years. Due to the pandemic, no climbing of the structures is allowed. They are trying to discourage crowding in the rooms of the Palenque structures. The other major change underway is the construction of a large complex of buildings a bit further down the road meant to serve as the entrance to the park and the place where vendors and the ticket booth will be located.

While this activity is going on in the central core of the site, our team has been working hard to initiate excavations in residential groups immediately surrounding this area. Rodrigo has a small team to continue working in Group IV, where they have already cleared away the east side of the mausoleum structure J6, revealing the inset corners that mirror the west side of the structure. There also appears to be a low platform that abuts the structure on the east side where there may be more burials as part of the cemetery in the plaza.

To the west of Group IV (and across the road), Arianna and Lisa have opened up excavations in two residential groups on the outer edges of our proposed “neighborhood.” The structures back up to the Motiepa and would have had convenient access to water. Consequently, for our team, it makes for a beautiful setting to work in! Already, it is clear that these residential groups are not the homes of Palenque commoners. In just one week, Lisa and her team have defined the perimeters of a large stone structure and a large concentration of figurines, decorated pottery, large obsidian blades, fragments of an alabaster box lid and what appears to be mirror back fragments.

While Lisa and her team clear the large, complex structure of JO33, Arianna and her team are working in the group immediately south of it and they are also finding figurines, the most recent, including an elegant bat figurine and a god head.

Already, we are seeing whole obsidian blades with very little use, and hachas, of chert and limestone. We will continue to look for the suite of materials suggesting the kinds of activities that were occurring in this household group.

Next week, we will continue to define the architecture of structure JO33, and look for occupational surfaces to sample for micromorphology, paleoethnobotany and soil chemistry. Let’s just hope the weather holds out.
