A beautiful little park. If you are going to go to St. Patrick's Cathedral, you will be in the park. Very well maintained and pleasant.
Right behind the Saint Patrick's Cathedral is a beautiful park which unlike the Cathedral itself is free for all to enjoy! I recommend stopping in at the cafe "Bite of Life" right next to the park to grab a drink, snack or lunch and have a picnic in the park. Very nice!
A very well-conserved and very green park with banks to sit to look at one of the sides of the Saint Patrick church. It is true that it has no trees that give shadow, but also in Dublin you don't need them because when there is no sun is so strong and everyone is thrown out of the shadow. It is a very relaxed place, if you are tired of the tour through the centre of Dublin is a good place for rest.
