It is very close to Stephen’s Green Park, which is the most popular park in Dublin (I’d say followed by the Phoenix Park). I guess that this is one of the reasons why Iveagh Gardens doesn’t have as many visitors, apart of it being quite hidden as it is surrounded by buildings.
This park has a hedge maze, it’s like a small plant labyrinth, I’d say a small dog could get lost in it.
There is two nice fountains and on the west part of the park and a very beautiful cascade, it is great to look at it in summer, if it’s not raining.
Something funny about the Iveagh Gardens is that there is a sundial, which tells the time with the position of the sun, however, most of the time it doesn’t work as it’s cloudy, which as you may know it is very common in Ireland.
Iveagh Gardens also host many events, such as Taste of Dublin, and lots of concerts by bands from all over the world.
Lay on the grass and relax!
