The site has four galleries with information on building techniques used by the ancient Maya. Many of the pieces come from collapsed and rescued facades, while others are monoliths bearing important symbols that were part of the architectural ornamentation.

The first gallery has two great Puuc-style stucco corner facade masks from Miramar, each made from several large stones. They are accompanied by stelae from Itzimte and sculptures from Xcalumkin, Xcocha, Dzibilnocac and Cayal, all sites in the north of Campeche. Texts explain how to read the hieroglyphs and the associated dates.

In the entrance to the second gallery there is a display showing a governor of Calakmul (520-546 AD) commencing a dance ritual. Inside, the figure of the god Itzamna from Chunhuhub seems to be presiding over a meeting of pieces including a column with musicians and dwarfs, a stela from Edzna, atlantes from Xculoc, columns decorated with large glyphs and a square frame from Xcalumkin.

In the next gallery there is a Río Bec bench with a stucco covering and vestiges of color accompanying small columns with reliefs of deities and the lining of a vault painted with the image of Kawiil, the god of ancestry and abundance. This latter is remarkable because one of his feet is in the form of a snake. These pieces come from Santa Rosa Xtampak. At the other end we can see a stela from Dzehkabtun with the skeleton of a deer and a sculpture of an official from Dzibilnocac.

The last gallery of the Bastion of Soledad is dedicated to Calakmul, particularly to the funerary offering recovered from a tomb in Structure VII, where the first of the site’s jadeite, shell and obsidian masks was found. This archeological gem has been included in numerous international exhibitions. It is accompanied by land and sea shells, bowls, plates and cups, some of which even have a spilled substance that has solidified over time, possibly copal.
