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.

The Medway Megaliths, sometimes termed the Kentish Megaliths, are a group of Early Neolithic chambered long barrows and other megalithic monuments located in the lower valley of the River Medway in Kent, South-East England. Constructed from local sarsen stone and soil between the 4th and 3rd millennia BCE, they represent the only known prehistoric megalithic group in eastern England and the most south-easterly group in Britain.
