Tsunamis, rabbit warrens and shell-rich sand: a guided walk at Rosscarbery

The impact of the tsunami, which followed the 1755 Lisbon Earthquake, is well remembered along the West Cork coast. Why is this? Of course, it might be expected that such an unusual flood event would become established in folklore. But another reason must be because the sand dunes at various locations were modified, threatening the industries that were associated with them, because the 'sand hills', as they were known then, were a precious resource. At the time of the Lisbon Earthquake, rabbit warrens were established at several locations near Rosscarbery. Furthermore – and as had been the case for centuries – shell-rich sand was being laboriously mined and brought by horse-drawn carts to nearby farms where it was used to improve the clayey soil.

The purpose of the excursion, which will be led by local geologist Anthony Beese, will be to explore the cultural landscape associated with the sand dunes. Wear suitable footwear and clothing for a four-kilometre walk of moderate difficulty. Registration is necessary. If possible, arrive early and bring a picnic lunch.
