This national monument and is located facing the entrance to the Punchestown Racecourse in Co. Kildare. It hugely elegant stone stands 15-feet high and would not look out of place in a modern landscaped designers garden. Kildare has a number of long stones and it was often believed that they might be boundary markers or scratching posts erected by farmers for animals. The nearby Punchestown Longstone however toppled over in 1933 exposing a small cyst grave that contained cremated bones and grave goods. These probably belonged to a local chieftain who lived sometime between the late Bronze Age and early Iron Age (500BC-1500BC) and confirmed that these stones were ancient grave markers.
