Poll na Seantoine, a cavernous blow-hole, which has been hollowed out by the unrelenting wave action of the Atlantic Ocean, is an awe-inspiring sight, its sheer walls reaching nearly 30 metres down to the churning waters. Some years ago a small monument was erected as a memorial to several men who are reputed to have died there, after the 1798 uprising. They had taken refuge in the cavern to avoid the Redcoats who were pursuing them, but were trapped by the incoming tide and all drowned.
