Merimde Beni Salama is a Neolithic settlement in Egypt, in the West delta of the Nile, 45 km northwest of Cairo. It is the typesite of Merimde culture. The settlement was occupied for about 800 years, from around 5000 to 4200 BC. The population may have reached as many as 16,000. The site represents the earliest evidence for a fully sedentary settlement in the Nile valley.[1]
