Killagha Abbey, also known as Kilcolman Abbey, was erected on the side of an older monastery around the 12th century. It was a very wealthy Abbey and held a lot of local power and had connections with the Irish House of Lords. Unfortunately, it was a victim to Cromwell's soldiers and never able to regain its former glory. This was once a very impressive building and traces of its architecture can still be seen to this day. Only the church with a single long nave remains, as well as the associated graveyard, but one can visit and view the well known East Window which was restored by a local community group.
It is situated outside Milltown Village, on the banks of the River Maine, just off the N70 road.
If you have some free time, discover the nearby Killaclohane Wood, where there is a Mass Rock which is reputed to have special powers. According to local lore, it is said that lying by the rock for 10 minutes is equal to 8 hours of restful sleep.
