"Manning Tower" or "Monning Tower" near Marino Point on Great Island in Cork Harbour. This Martello Tower is one of a number built in the 19th century to defend the strategically important harbour. Manning Tower is one of very few Martello Towers (if indeed there were any others) to be taken by force - when it was held briefly during the 1867 Fenian Rising.
