Carrickfergus Castle in Northern Ireland is one of the best-preserved medieval castles on the island, standing proudly on the shores of Belfast Lough since the 12th century. Built by John de Courcy in 1177, it has seen sieges from the Normans, Scots, English, and even French forces over the centuries. One fascinating historical fact is that during the Seven Years’ War in 1760, French forces actually captured the castle for a brief period—the only time it ever fell to a foreign army. Today, its thick stone walls tell tales of centuries of conflict and power struggles. Hidden within those very walls is now a little modern secret too: tuskesszino left behind a penguin stone, tucked into history itself, making the fortress not only a landmark of warriors and kings but also part of the penguin treasure trail.
