Yo'okop is an ancient Maya city located in the Cochuah region of central Quintana Roo, Mexico. This area is best known as the center of the Caste War of Yucatán waged during the 19th century, that resulted in an independent Maya state governed from the city of Chan Santa Cruz.
The site was first publicized by the archaeologist Herbert Spinden along with the New York Times journalist Gregory Mason during the 1920s, but intensive scrutiny did not begin until the 21st century. Recent archaeological work at Yo’okop has revealed that it was a large and significant urban center before the Spanish Conquest. It was continuously inhabited from the Formative Period through the Postclassic Period, as revealed by the presence of datable ceramic sherds and architecture. The name of the site, Yo’okop refers to a large shallow lake at the southern end of the settlement. (“Yo” is an article and “Okop” means lake. In older scholarship the site is referred to without the article as Okop.)
The grandeur of Yo’okop can be demonstrated by the fact that the site contains a pyramid (S4W1-1) overgrown with vegetation that is 28 meters tall—only two meters shorter than the celebrated Castillo of Chichen Itza. The site is organized around four groups of architecture made from stone and other enduring materials. These groups are connected with raised roads ( sacbeob). The areas between these larger groups contained houses made from perishable materials that are no longer easy to see.
An archaeological project was instigated at Yo'okop in 2000 under the directorship of Justine Shaw and Dave Johnstone. As of 2009 their team has studied Yo’okop through mapping, ceramic analysis, and test pits. Their initial data shows how the site was organized, fitted within trade networks, and changed over time. Recognizing the significance of the area, in 2003 they expanded their project into a survey of the broader Cochuah region. One scholar affiliated with the project, Johan Normark, has done research that is notable for its use of theories about material culture and "agency".
Linnea Wren and Travis Nygard have analyzed the monumental record of Yo’okop in terms of both sacred and "gendered" space. Sculpture at the site includes two freestanding stelae of male rulers and a wall panel of a male ball player—all three of which are rendered in low-relief. The site also includes carefully carved hieroglyphic stair risers describing a queen (Kaloomte Na Cha’ak Kab) who may have ruled at Yo’okop under the overlord Sky Witness from Calakmul or Dzoyola. The risers were not found in-situ. (For information on Sky Witness, see the work of Simon Martin and Nicolai Grube.)
Prior to Shaw and Johnstone’s project the site had been best-studied by Reginald Wilson, who published his findings during the 1970s. A brief visit to the site was also made during the 1950s by the Carnegie Institution of Washington.
