Polished stone axehead found in Roscam on the outskirts of Galway city. Polished stone axeheads were commonly used tools in the later Mesolithic and throughout the Neolithic periods in Ireland – this particular axehead is likely Neolithic dating to between 3800 BC to 2000 BC. It would have been mounted on a wooden haft and secured with animal sinew or leather and resin. With its well-shaped cutting edge, it made an effective chopping tool.
