Ystum-Cegid Burial Chamber is a prehistoric chambered long cairn located in Wales and protected as a scheduled monument by Cadw under reference CN029. The monument is built upon bedrock of Ordovician age, composed of felsic tuff, a volcanic rock formed from compacted ash and fine rock fragments erupted during the Ordovician period, over 440 million years ago. This ancient geology provides the native stone from which the chamber structure was constructed.
The burial chamber belongs to the class of Neolithic long cairns, monuments erected during the early farming period in Britain, typically between 4000 and 3000 BCE. These structures served as collective repositories for the dead, with stone chambers built at the centre or along the length of elongated earthen and rubble mounds. The internal chambers at such sites often feature orthostatic stones—large flat slabs set upright to form walls and compartments—arranged to create accessible burial spaces within the larger cairn mass.
The monument's preservation under Cadw protection reflects its importance as a record of early Welsh settlement, burial practice and the landscape use of Neolithic communities. Archaeological monuments of this type across Wales demonstrate the spread of megalithic tomb construction during the early Neolithic, representing a significant shift towards sedentary settlement and organised communal ritual in prehistoric society.
