Step 1 : Introduction to the question "2. So the first settlers in Ireland were leprechauns, right? Sorry, no. The oldest settlement discovered by archeology in Ireland is this place that sounds like something you might wear to the beach. Which site is it?"
...1. Lough Truncha 2. Mount Brandon 3. Mount Sandel 4. Lough Gara It is believed that humans first came to Ireland around 8000 BC during the Mesolithic era. Although this earlier date is suspected, the earliest evidence for human habitation comes from charcoal remains found at Woodpark in County Sligo that date to 7490 BC. Another site at Lough Boora in County Offaly dates to around 6800 BC but again no structures or permanent settlement buildings were found. It is believed it was a temporary camp site, most probably a summer one. The oldest settlement evidence has been found at Mount Sandel in County Derry and dates back to 7000 BC. This site also shows signs of consistent habitation and possible rebuilding of structures. It is located near the iron age site of Mount Sandel Fort (Kill Santain or Kilsandel). The fort site is believed to have been the residence of the Norman king John de Courcy in the 12th century AD.
