Topping the list is Kilkenny Castle for the second year in a row with over three quarters of a million visitors. It's follow closely by Glendalough with over 732 thousand people making the trip to the County Wicklow site.
Earlier this week it was confirmed that tourist numbers from Britain, the US and Canada have dropped in the last year but this list shows that home grown attractions are still a big draw.
Third most popular was The Botanic Gardens in Dublin with just under 656 thousand people taking in its sights.
The gardens were also the most popular of all OPW sites in Dublin.
