Little Kit's Coty House

Little Kit's Coty House, also known as Lower Kit's Coty House and the Countless Stones, is a chambered long barrow located near to the village of Aylesford in the southeastern English county of Kent. Constructed circa 4000 BCE, during the Early Neolithic period of British prehistory, today it survives in a ruined state.

Archaeologists have established that the monument was built by pastoralist communities shortly after the introduction of agriculture to Britain from continental Europe. Although representing part of an architectural tradition of long barrow building that was widespread across Neolithic Europe, Kit's Coty House belongs to a localised regional variant of barrows produced in the vicinity of the River Medway, now known as the Medway Megaliths.
