Carrowmore – the largest cemetery of megalithic tombs in Ireland. It lies just south-west of Sligo town, right at the heart of the Cúil Írra Peninsula, an area alive with prehistoric significance. Packed together at Carrowmore are more than 30 stone tombs, many of which are still visible. Most are passage tombs and boulder circles. There are various forts and standing stones in the area too. The origins of these monuments reach far into prehistory – the most ancient among them is close to 6,000 years old.
