context_page_description: County Mayo is a county in Ireland. In the West of Ireland, in the province of Connacht, it is named after the village of Mayo, now generally known as Mayo Abbey. Mayo County Council is the local authority. The population was 130,507 at the 2016 census. The boundaries of the county, which was formed in 1585, reflect the Mac William Íochtar lordship at that time.
context_section_description: There is evidence of human occupation of what is now County Mayo going far back into prehistory. At Belderrig on the north Mayo coast, there is evidence for Mesolithic (Middle Stone Age) communities around 4500 BC. while throughout the county there is a wealth of archaeological remains from the Neolithic (New Stone Age) period (ca. 4,000 BC to 2,500 BC), particularly in terms of megalithic tombs and ritual stone circles.
  The first people who came to Ireland – mainly to coastal areas as the interior was heavily forested – arrived during the Middle Stone Age, as far back as eleven thousand years ago. Artefacts of hunter/gatherers are sometimes found in middens, rubbish pits around hearths where people would have rested and cooked over large open fires. Once cliffs erode, midden-remains become exposed as blackened areas containing charred stones, bones, and shells. They are usually found a metre below the surface. Mesolithic people did not have major rituals associated with burial, unlike those of the Neolithic (New Stone Age) period.
  The Neolithic period followed the Mesolithic around 6,000 years ago. People began to farm the land, domesticate animals for food and milk, and settle in one place for longer periods. These people had skills such as making pottery, building houses from wood, weaving, and knapping (stone tool working). The first farmers cleared forestry to graze livestock and grow crops. In North Mayo, where the ground cover was fragile, thin soils washed away and blanket bog covered the land farmed by the Neolithic people.
  Extensive pre-bog field systems have been discovered under the blanket bog, particularly along the North Mayo coastline in Erris and north Tyrawley at sites such as the Céide Fields, centred on the northeast coast.
  The Neolithic people developed rituals associated with burying their dead; this is why they built huge, elaborate, galleried stone tombs for their dead leaders, known nowadays as megalithic tombs. There are over 160 recorded megaliths in County Mayo, such as Faulagh.
