Most of the heritage sites you’ll see in Ireland, such as castles and other attractions, are run by the Office of Public Works.
Several of them are normally free to visit, and some are also free to visit on the first Wednesday of each month.
However, the more popular ones like Kilmainham Jail in Dublin, The Rock of Cashel in Co. Tipperary, the Brú na Bóinne Visitor Centre in Co. Meath, which includes Newgrange and Knowth, as well as Kilkenny Castle, among others, are paying attractions.
Here are some of the lesser-known heritage sites in Ireland that are also worth seeing.
Battle of the Boyne/Oldbridge Estate, Co. Louth
The Battle of the Boyne between King William II and the deposed King James II (his father-in-law) is a watershed moment in Irish history and the iconic battle and its consequences are retold at the heritage site known as the Battle of the Boyne Visitor/Oldbridge House.
The battle was fought on July 1, 1690.
The Williamite side had 36,000 troops and the Jacobites had 25,000.
In total, it was the largest number of troops ever deployed on Irish soil. James ultimately lost that battle, which of course meant he was unable to regain the British crown.
More importantly for Ireland, it meant the continuance of the Protestant ascendancy for centuries to come.
The visitor center is located in the restored 18th-century Oldbridge House, which is on the battle site.
The center runs specific guided tours throughout the year that are announced beforehand. Otherwise, a self-guided tour through the center's exhibition space will provide you with a good history of the battle.
Admission is a nominal €5 for adults, €4 for students and seniors, €3 for children under 12, and €13 for a family.
Blasket Centre, Dingle, Co. Kerry
The center tells the story of island life and how the community survived on fishing and farming, as well as the literacy legacy that emerged.
The center contains exhibitions, interactive displays, artifacts, audiovisual presentations, and more.
Admission to the center is as follows: adult (€5), senior/group (€4), child/student (€3), and family (€13). Children under 8 are free.
Carrowmore Megalithic Cemetery, Co. Sligo
This is the largest site of megalithic tombs in Ireland.
There are 30 that remain today.
Archaeologists believe the monuments, which are about 6,000 years old, were built and used by people who came to Sligo from Brittany in northwest France.
Reports of ongoing damage to this and other precious megalithic sites in Sligo were reported in the Irish press.
Admission to gain entrance to the Carrowmore Megalithic Cemetery Visitor Centre is €5 for adults, €4 for seniors, €3 for children and students, and €13 for a family ticket.
Castletown House & Parklands, Co. Kildare
Castletown House is an imposing Palladian estate located in the County Kildare countryside, the largest and most significant of its kind in Ireland.
The house, which is part of a 550-acre estate, was built between 1722 and 1729 for the Speaker of the Irish House of Commons, William Connolly.
It was designed by the famous Italian architect of the time, Alessandro Galilei.
Some say it inspired the design of the White House, which was overseen by the Irish-born architect James Hoban.
This is one of Ireland's heritage sites you shouldn't miss.
Ceide Fields, Co. Mayo
This is the most extensive Stone Age site in the world revealing stone wall field systems, dwelling areas, and megalithic tombs.
Believed to be about 6,000 years old, the site was covered under a blanket bog until the 1930s when a local schoolteacher noticed a pile of stones at the bottom of the bog while cutting turf.
Forty years later, his son, an archaeologist, would confirm what was really under the bog.
The heritage site's award-winning visitor center is a must-see. Admission is €5 for adults, €4 for seniors, €3 for children under 12, and €13 for a family of 4.
Charles Fort, Co. Cork
This 17th-century star-shaped fort located in Kinsale Harbor is one of the largest military installations in Ireland.
It has been associated with some of the country’s most momentous events, including the Williamite War of 1689-91 and the Irish Civil War of 1922-23.
Self-guided tours can be booked on the Charles Fort website. According to the website, guided tours are an option but visitors must enquire at the reception when they arrive as some are not available year-round.
General admission is as follows: adults €5, groups/seniors €4, children/students €3, and €13 for a family of 4.
Clonmacnoise, Co. Offaly
Founded by St. Ciaran, Clonmacnoise was once a major center of religion in Ireland beginning in the 9th century.
In fact, from the 9th through 11th centuries, it was the burial spot of choice for some of the country’s most important people, including Turlough O’Connor, King of Connacht, and his son Rory who are reputedly buried there.
After numerous raids by the Vikings, the native Irish and the Normans, Clonmacnoise was largely abandoned by the end of the 13th century.
Today the site located on the banks of the River Shannon includes nine ruined churches, two round towers, a castle, as well as several stone crosses and cross slabs.
The most well-known of its artifacts includes the Cross of the Scriptures (a replica is outside, but you can find the original in the visitor’s center).
The 4-meter (13-foot) cross is one of the most beautiful in Ireland, displaying scenes from the Crucifixion, the Last Judgment and Christ in the tomb.
This peaceful site is open year-round except on Christmas Day.
Desmond Castle, Newcastlewest, Co. Limerick
Not to be confused with Desmond Castle Adare, this imposing two-story structure once used by the Earls of Desmond was built in the 15th century.
The banqueting hall is the most impressive aspect of the castle, which was partly restored during the 20th century.
Its features include an oak musicians’ gallery and a limestone hooded fireplace.

It is located on the edge of a cliff that rises 100 meters (330 feet) from the ocean.
The fort consists of three massive dry-stone walls and a series of jagged, upright stones.
