Kylmore Abbey is one of the favourite destinations of Connemara.  This lovely mansion was built by a man for his loving wife.  After her death, he built the cathedral in her honour, just minutes walk from the amazing house.
If you decide to go, I suggest taking the trip via Lally Tours.  It's a Day Trip of Connemara which takes you to lovely Leenane Village, as well as other picturesque locations.
