The Magic of Celtic Christianity
The round towers of Ireland were carefully placed to reproduce the circumpolar star positions. To be able to do this in the 1100's is an amazing feat. There is speculation that the Towers were tuned to a low resonance which influenced the growth of produce in the surrounding territory. There Abbeys and Churchs
were placed over the crossing of underground water courses discovered by dowsing. An engineer who was associated with the beacon of low frequency that guided the Sunderland aircraft returning to Loch Erne
airbase recognized the possible use of the Towers.
