Excavations at the Glandy Cross monumental complex during 1991 and 1992 formed part of an integrated programme of evaluation, rescue, and research by Dyfed Archaeological Trust (DAT). Enclosures, pit circles, standing stones, and cairns were excavated and their environs systematically surveyed. Radiocarbon dates show the monumental complex to have been constructed between c. 2190–1530 cal BC. However, the earliest activity at the site may date to c. 4470–4230 cal BC. A defended enclosure was constructed on the peripheries of the complex c. 830–510 cal BC.
The 1991–92 excavation results are presented along with a summary of survey, salvage, and research spanning the period 1981 to 1992. This new data set is tentatively interpreted in terms of historical process and the social practice of monumental construction. A brief commentary on heritage management at Glandy Cross is also presented.
A note on authorship: one of the authors (George Williams) directed the Glandy Cross excavations during 1991–92 and prepared an initial draft of the project report. Following his retirement from DAT a project editor (Trevor Kirk) was commissioned by Cadw: Welsh Historic Monuments to guide the project towards publication. This paper was largely penned by the project editor, though the excavation and survey data were produced by George Williams and his fieldwork team. The excavation and survey archives are held at the offices of DAT.
