“Free entry” in Ireland means three different things, and mixing them up is why people pay at gates they did not have to.
There are attractions that never charge, and a surprising number of the best ones are in that group. There are calendar days when sites that normally charge do not. And there are entitlements, based on age or circumstance rather than on a date, that apply whenever you turn up.
Nobody publishes all three together. The Office of Public Works knows about its own 45-odd sites and posts the Free Wednesday list on its own page. National Heritage Week and the August under-18s scheme get announced in separate press releases each year and are gone from the front page within a week. The always-free national institutions are run by different bodies and never appear on one list. This page is that list.
The free days worth planning around
| When | What | Where |
|---|---|---|
| First Wednesday of every month | Free admission at around 40 fee-paying OPW heritage sites, for independent visitors and families. No online booking, first come first served, not valid for group tours. | Republic of Ireland |
| The opening Saturday of National Heritage Week, mid-August | Free admission at over 50 OPW sites. In 2026 this was Saturday 15 August. | Republic of Ireland |
| All of August | Free entry for all under-18s at fee-paying OPW sites when accompanied by an adult. In 2026 it ran 1 to 31 August, excluding Kilmainham Gaol and Brú na Bóinne. Announced annually. | Republic of Ireland |
| Culture Night, Friday 18 September 2026 | Thousands of free events, late openings and access to venues across the island, from 4pm into the night. | All of Ireland |
| European Heritage Open Days, 12 to 13 September 2026 | Hundreds of historic buildings and sites open free, including many normally closed to the public. | Northern Ireland |
| Sundays at the National Botanic Gardens | Guided tours are free on Sundays; they cost €5 the rest of the week, and the gardens themselves are always free. | Dublin |
Two honest caveats. The Free Wednesday scheme is the only one of these that is permanent and predictable; the August under-18s window and the Heritage Week free day are announced fresh each year and could change or stop. And dates in this table need checking against the current year before you build a day around them.
The OPW Free Wednesday site list
This is the list that is otherwise buried on a single page of the Heritage Ireland site, and the one most people never find. Around 40 fee-paying sites take part on the first Wednesday of each month.
| County | Site |
|---|---|
| Clare | Ennis Friary |
| Cork | Charles Fort, Ilnacullin (Garinish Island), Doneraile Court and Estate |
| Donegal | Donegal Castle, Glebe Gallery and Garden |
| Dublin | Casino Marino, Rathfarnham Castle, Custom House Visitor Centre |
| Galway | Athenry Castle, Aughnanure Castle, Dún Aonghasa, Pearse’s Cottage (Conamara), Portumna Castle and Gardens |
| Kerry | Ardfert Cathedral, Derrynane House, The Blasket Centre, Ross Castle |
| Kildare | Castletown House and Parklands |
| Kilkenny | Jerpoint Abbey |
| Laois | Emo Court and Estate |
| Leitrim | Parke’s Castle |
| Limerick | Adare Castle |
| Louth | Old Mellifont Abbey |
| Mayo | Céide Fields |
| Meath | Battle of the Boyne, Oldbridge Estate, Trim Castle |
| Roscommon | Boyle Abbey |
| Sligo | Carrowmore Megalithic Cemetery, Sligo Abbey |
| Tipperary | Cahir Castle, Ormond Castle, Roscrea Castle and Damer House, The Swiss Cottage |
| Waterford | Reginald’s Tower |
| Wexford | The John F. Kennedy Arboretum, Tintern Abbey |
| Wicklow | Glendalough Visitor Centre |
Note what is not on it. The three biggest earners, Brú na Bóinne, Kilmainham Gaol and Dublin Castle, do not take part, and neither does the Rock of Cashel. If those are what you came for, the free Wednesday will not help and the Heritage Card is the better tool.

The genuinely useful list, because it does not depend on a date. Ireland’s national collections are free as a matter of policy, and most county museums follow suit.
National institutions
| Place | County | Note |
|---|---|---|
| National Museum of Ireland | Dublin, Mayo | Free at all four sites: Archaeology on Kildare Street, Decorative Arts and History at Collins Barracks, Natural History on Merrion Street, and Country Life at Turlough Park, Castlebar. |
| National Gallery of Ireland | Dublin | Permanent collection free. Some temporary exhibitions charge. |
| Chester Beatty | Dublin | Free, with a suggested €10 donation. In the grounds of Dublin Castle, which does charge. |
| Irish Museum of Modern Art | Dublin | Free, at the Royal Hospital Kilmainham. Special exhibitions may charge. |
| National Library of Ireland | Dublin | Free, including the exhibitions. |
| Ulster Museum | Antrim | Free, and the largest museum in Northern Ireland. |
| Linen Hall Library | Antrim | Free, suggested £3 donation. Belfast’s oldest library. |
County and city museums, free to walk into
| Place | County |
|---|---|
| Galway City Museum | Galway |
| Limerick City Gallery of Art | Limerick |
| Glucksman Gallery | Cork |
| Cobh Railway Station, the Queenstown Story | Cork |
| Down County Museum | Down |
| Sligo County Museum | Sligo |
| Monaghan County Museum | Monaghan |
| Highlanes Gallery, Drogheda | Louth |
| Irish Linen Centre & Museum, Lisburn | Antrim |
| Armagh Robinson Library | Armagh |
| Curragh Military Museum | Kildare |
| Adare Heritage Centre | Limerick |
Two of the best free galleries in the country are shut. The Crawford Art Gallery in Cork closed in September 2024 for a major redevelopment and is expected back in 2027; the Hugh Lane Gallery in Dublin is closed until 2028. Both are free when open, and both still turn up on other sites’ free-things-to-do lists.
OPW sites that are free every day
This is the distinction the Heritage Card question turns on, and it is the one the official listings blur. A good number of OPW properties charge nothing to anyone, card or no card, so they belong on a free list rather than a pass-comparison one.
- St Stephen’s Green, Iveagh Gardens, Phoenix Park, the Garden of Remembrance and the National Botanic Gardens, all in Dublin
- St Audoen’s Church, Dublin
- Kells Priory, Kilkenny, one of the largest medieval monastic sites in Ireland and completely unstaffed
- Nenagh Castle and the Main Guard, Tipperary
- Maynooth Castle, Kildare
- Dungarvan Castle, Waterford
- Ballyhack Castle, Wexford
- Farmleigh, Dublin: grounds, gardens and gallery are free, and the outdoor guided tours are free with a complimentary ticket
Free by entitlement, not by date
- Children under 12 get into OPW sites free all year, with no ticket and no card.
- Disabled visitors are admitted free to OPW sites. Accessibility arrangements such as parking and step-free routes are handled site by site, so contact the site ahead of a visit.
- English Heritage members already have free entry to all OPW sites, which is worth knowing before buying a second card.
- National parks are free, all of them: Killarney, Connemara, the Wicklow Mountains, Glenveagh, Wild Nephin and the Burren. Parking sometimes costs money and buildings inside them, such as Muckross House, charge separately.
- Most public parks, forest parks and beaches charge nothing to walk into, though car parking is the usual charge point: Lough Key Forest Park is free to enter with €6 per vehicle to park, and Glenariff in Antrim is free on foot with £5 per car.

The free routes and the paid pass solve different problems, and the honest comparison is short.
- Living here, or one county at a time? The first Wednesday of the month plus the always-free institutions will cover most of what you want, at no cost.
- Touring for a week or more? You cannot line up a fortnight of visits behind one Wednesday, and the free day excludes the big three. The OPW Heritage Card at €40 for an adult is the instrument for that trip, and it pays for itself at roughly four expensive sites or eight cheap ones.
- A weekend in Dublin? Neither. The free national museums and galleries are the best value in the city, and the paid attractions people actually queue for, Kilmainham Gaol, the Book of Kells, the Guinness Storehouse, are not covered by any of the free schemes. See Dublin’s attraction passes compared for whether a city pass earns its keep.
Free-day dates change every year. This page was checked in August 2026; treat the Culture Night, Heritage Week and August under-18s entries as needing confirmation against the current year before you travel.
