Glendalough Cathedral 30 Miles South of Dublin. St. Peter and St Pauls’ Cathedral Achonry,[1] is a former cathedral[2] in the Republic of Ireland:[3] It is within the same enclosure as Our Lady’s Church and the Round Tower.[4]
My source for this measure- 110 feet in height – is the book, Riddles in the British Landscape. It has 148 illustrations and 4 maps. The book is written by Richard Muir, p. 183. Publisher is Thames and Hudson, London, 1981.
Glendalough Cathedral has a Tower Built by a Hidden Number Square Code

Masonic symbol is traceable to the basic number square of antiquity. 110 is found here. Feet are assigned to this figure. Why is this number square Masonic? A pattern outlines a Masonic symbol. We have nine numbers. Take the numbers three at the time as follows:
- At a slant, 1, 2, 3 gives you the top triangle of the compass.
- 7, 8, 9 offers the reciprocal bottom triangulated half of the “T” square.
- Finally, 4, 5, 6, offers the slanted diagonal. Again these numbers are tilted in the number square. In the Masonic symbol above it occupied by “G”.

So where is the 110 used at the Glendalough Round Tower? It seems like the square only goes up to nine. But, consider the numbers in the following manner: Two at the time by opposite polarities. We now have:
- 49 + 61 = 110
- 94 + 16 = 110
- 95 + 15 = 110
- 45 + 65 = 110 etc.
Finding the Hidden 110 at the Glendalough Cathedral
For those who care to go thru the trouble and time, 110 can be found in sixteen different ways on this simple number square. The total of all 16 becomes 1,760. Those who know measurement can recognize 1,760 is another number of measurement: There are exactly 1,760 English yards in one mile. Three feet are in the yard. There are 5,280 feet in the mile. Thus, 5,280 ÷ 3 = 1,760.
Why go through all this trouble? This number square once marked a lost Golden Age of Peace and Plenty. This code needs to be reactivated. Why shouldn’t we all have the same today? The tower at Glendalough Cathedral would then become the symbol of good things to come.
