As part of my dissertation entitled Documenting Cultural Transition Through Contact Archaeology in Tíhoo, Mérida, Yucatán (Rogers 2010), I conducted the first systematic archaeological study of the Ciudadela (YUC 2) artifact assemblage – originally collected from Tíhoo/Mérida by Dr. John Goggin in 1956 and 1957 and currently housed in the J. C. Dickinson Hall Research Center at the University of Florida–Florida Museum of Natural History (hereafter referred to as FLMNH). As one of the last standing structures in the Maya site of Tíhoo, now buried beneath the San Benito Marketplace in the Yucatán capital city Mérida, the Ciudadela collection represents a rare glimpse into a significant, yet understudies, Type 1 archaeological site. The purpose of this study was to develop a tentative chronological sequence for the site’s cultural occupations, to determine the impacts of Spanish contact, and to illustrate the material connections between the communities occupying this site. I described and quantified formal and decorative elements of style for both precolumbian and historic remains and grouped them into pre-existing cultural and artifact chronologies in order to identify site function, use, and patterns of cultural interaction occurring at this site.
