Some of the locations of the earliest Culdee churches were sited near or on top of what used to be important Pre-Christian sites. In Ireland, a notable example is when Saint Patrick choose to build his first stone church in Ireland, he decided to build it as close as possible to the Ancient Druidic site of Emain Macha. The oldest of the two Cathedrals in Armagh is located on a steep sided hill which Queen Macha allegedly had chosen as a defense of the ancient Fortress at Emain Macha in Pre-Christian times.
