Irish Castles You Can Explore on a Cruise

Ireland is a place where the past and present exist side by side. In a single town, you might find a quiet centuries old church not far from a lively pub filled with music and conversation. From its rocky coastlines to its lively towns and verdant landscapes scattered with sheep, you’re always close to its ancient and mythical history. One of the best ways to explore Ireland’s history is through its castles — from crumbling ruins to well-preserved fortresses rich in legend.

There are over 30,000 castles in Ireland, which is even more impressive considering Ireland covers about 32,000 square miles, roughly the size of Maine. Wandering through ancient stone fortresses and exploring their legends and documented history inspires wonder at every turn. And if the mist should roll in, creating a hauntingly beautiful scene, know that it’s just Ireland showing off in the best way possible.

Tucked beside the bridge that connects the mainland to Great Island near Cobh, Belvelly Castle is one of those places you might almost miss if you’re not paying attention. This medieval tower house was built by the Anglo-Norman Hodnett family, probably in the 14th or 15th century, and once guarded the main route into Cork Harbour.

Over the centuries, it passed through several owners and is even believed to have been held by the explorer Sir Walter Raleigh in 1581. By then, the castle had already begun to fall into ruin. During World War II, the Irish Army briefly used it as an observation post. After decades of being abandoned, the castle was bought in 2016 and beautifully restored, giving this historic landmark a remarkable new chapter.

Kissing the Blarney Stone is a quirky travel tradition you may or may not want to pursue. Legend has it you’ll be bestowed with the gift of eloquence. There’s no evidence it will give you an irresistible way with words, but hey, it’s part of the fun. As one of Ireland’s best-preserved medieval fortresses, Blarney Castle offers much more than kissing an ancient stone. Wander the interior and explore the chieftain’s chambers and sprawling grounds. A visit to the Poison Garden is a must — home to belladonna, mandrake, and other deadly botanicals. Then venture to the Witch’s Kitchen, a moss-coated rock formation entangled with ancient roots that feels plucked straight from a fairy tale.

Nestled on a rocky island along the River Suir in County Tipperary, Cahir Castle is one of Ireland’s largest and best-preserved medieval fortresses. Built in the 13th century, it was the stronghold of the powerful Butler family and considered so formidable that it was widely believed that it could not be breached — a reputation that lasted until the Earl of Essex used heavy artillery against it in 1599. Much of the original structure still stands, though, which is why filmmakers keep coming back. The castle has been featured in numerous productions, including Excalibur and most recently, the popular Showtime series The Tudors. Walking the battlements and courtyards, it’s easy to see why.

Rising above the River Eske in the center of Donegal Town, Donegal Castle was built around 1474 by Red Hugh O’Donnell — leader of one of Ireland’s most influential Gaelic clans and depicted as a fiery redhead in artworks. Instead of surrendering it to English forces, O’Donnell dramatically set fire to the castle before fleeing to Spain in 1601.

It later became the property of English captain Basil Brooke, who added Jacobean windows and a manor wing, creating the intriguing architectural mix seen today. Tour the grand dining hall and picture the medieval feasts once hosted there. Outside, take a selfie on the charming throne carved from a tree stump — a small, delightful surprise that perfectly captures Donegal’s fun-loving character.
