1. Bunratty Castle: Co. Clare, Ireland
Bunratty Castle, situated in County Clare, stands as one of Ireland’s most celebrated and recognizable castles. While earlier settlements occupied the site, the present-day castle predominantly dates back to the 15th century. This imposing fortified tower house underwent extensive restoration in the 1960s, transforming it into a captivating historical attraction. Clad in gray stone, Bunratty Castle is meticulously furnished with 15th and 16th-century antiques, providing visitors with an immersive glimpse into the daily life of the powerful MacNamara family, who originally commissioned its construction. Guided tours allow exploration of the castle’s interior, while the renowned medieval banquets, held almost nightly, offer a unique and entertaining dining experience.
2. The Rock of Cashel: Co. Tipperary, Ireland
The Rock of Cashel, a majestic castle complex located in County Tipperary, is shrouded in myth and legend. Local lore recounts that this was the site where Aenghus, the King of Munster, was converted to Christianity by St. Patrick in the 5th century. Prior to this pivotal event, the High Kings of Ulster held court from the imposing rock. Later, they bestowed the sacred site upon the Catholic Church. The majority of the structures within the sprawling castle complex date back to the 12th and 13th centuries, showcasing remarkable medieval architecture. Visitors can explore the grounds, marvel at the intricate stonework, and absorb the historical significance that has made the Rock of Cashel one of Ireland’s most popular tourist destinations.
3. Dunluce Castle: Co. Antrim, Northern Ireland
Perched dramatically atop a cliff overlooking the turbulent sea in County Antrim, Northern Ireland, lies the abandoned medieval fortress of Dunluce Castle. Its striking location and evocative ruins have earned it recognition as a filming location for the HBO series "Game of Thrones." The castle’s strategic setting, surrounded by sheer cliffs, made it a formidable defensive stronghold, accessible only via a bridge connecting it to the mainland. Originally constructed by the MacQuillan family in the early 16th century, Dunluce Castle was seized by the warrior MacDonnells in the 1550s. While its clifftop location provided excellent defenses, it also proved to be its undoing. A portion of the kitchen famously collapsed into the ocean during a violent storm in the 1630s. Eventually, the castle fell into disrepair after passing into the hands of the Earls of Antrim. Today, a visitor center provides historical context before visitors wander through the atmospheric ruins, imagining life within its weathered walls.
4. Blarney Castle: Co. Cork, Ireland
Blarney Castle, a medieval fortress situated near Cork, Ireland, is renowned for its picturesque setting amidst expansive gardens and the tranquil River Martin. The castle’s origins trace back to the early 13th century, although the current stone structure was erected by the McCarthy family in the 15th century. Visitors can explore several of the castle’s chambers and, of course, seek out the legendary Blarney Stone. Set high atop the castle walls, this stone is believed to bestow the "gift of the gab" upon those who brave the precarious lean and kiss it.

Unlike many of Ireland’s castles that exist as ruins, Ashford Castle in County Mayo has been transformed into a luxurious hotel. Originally constructed in the 13th century, the castle’s fortified walls were expanded over the centuries, witnessing fierce battles and strategic sieges. Following a truce, Ashford Castle served as a hunting lodge before being acquired by members of the Guinness family in 1852. The renowned Irish brewing dynasty expanded the castle, adding new wings and enhancing its grandeur before eventually selling the property in the 1930s.
