On the first Wednesday of every month, various heritage sites managed by the Office of Public Works that normally charge admission throw their doors open for free. So it won’t cost you anything to bring the family to the State Apartments in Dublin Castle and Kilmainham Gaol in Dublin; Brú na Bóinne Visitor Centre (Newgrange and Knowth) or Trim Castle in Co Meath – to name just a few.
