The first modern explorations of the site were conducted by
Thomas Gann in the mid-1890s. Gann moved from Britain and served as the district surgeon and district commissioner of Cayo,
British Honduras, starting in 1892. He chose this area to settle in due to his interest in Maya archaeology and the unknown wonders of the indigenous people that occupied the area. Gann's successor,
Sir J. Eric S. Thompson, implemented a more methodical approach, and was able to establish the region's first ceramic chronology in 1942. In 1959–60, the Cambridge Expedition to British Honduras arrived in the colony, and its archaeologist member,
Euan MacKie, who carried out several months of excavation at Xunantunich. He excavated the upper building on Structure A-11 in Group B and a newly discovered residential structure, A-15, just outside the main complex. Using the European method of detailed recording of the stratigraphy of the superficial deposits (the masonry structures themselves were not extensively cut into) he was able to infer that both buildings had been shattered by a sudden disaster which marked the end of the Classic period occupation. An earthquake was tentatively proposed as the cause; it is inferred purely on the basis of the excavated evidence, and also on the very damaged state of the top building of Structure A-6 ('El Castillo'). MacKie was also able to confirm the later part of the pottery sequence constructed by Thompson. The detailed report by MacKie is "Excavations at Xunantunich and Pomona, Belize, in 1959–60". British Archaeological Reports (Int. series), 251, 1985: Oxford. The main recent archaeological teams to work at Xunantunich and the surrounding region are the Xunantunich Archaeological Project (XAP), the Xunantunich Settlement Survey (XSS), and the Belize Valley Archaeological Reconnaissance Project (BVAR). Farmers that fed the occupants of Xunantunich typically lived in small villages, divided into kin-based residential groups. The farms were spread out widely over the landscape, though the center of Xunantunich itself is rather small in comparison. These villages were economically self-sufficient, which may be the reason why Xunantunich lasted as long as they did; they were not dependent on the city to provide for them. Other nearby Maya archaeological sites include
Chaa Creek and
Cahal Pech,
Buenavista del Cayo, and
Naranjo. ==Chronology==
