For me, this "mystery" began in the early 90s when I came across HOLY BLOOD, HOLY GRAIL and found the conclusions amazing. Did Jesus really survive the cross, to go on to father children to have the bloodline still survive to this day, hidden in plain sight? That was really something when I read it way back then. But continued examination of the thesis found several errors in the author's scholarship and serious abuses and artistic license with the New Testament and Jesus scholarship. It was George Sassoon (author of the MANNA MACHINE) who first informed me of the problem with HOLY BLOOD, HOLY GRAIL that forced me to look further. Ironically, Sassoon had his own artistic license with the Old Testament in contemplating his machine in the Ark of the Covenant that created human edible algae for the Israelites survival in the dessert. But I digress.
Despite my dismissal of the conclusions in HOLY BLOOD, HOLY GRAIL, I felt there indeed was a mystery yet to be discovered. There was something going on with Sauniere and Rennes-le-Chateau, even if it turned out the mystery was nothing more than the priest obtained his fortune through good old-fashioned fraud of selling masses (many never even delivered). So leaving the excessive baggage of Jesus, the Prior of Sion and all the baggage that came with HOLY BLOOD, HOLY GRAIL, and exploration of Rennes-le-Chateau itself is still a worthy puzzle. And this is where THE HOLY PLACE lives.
What are we to make of the church's alignments with surrounding mountains and other castles and churches in the area? Was there any purpose in this and what's the significance if so? By that, I mean, are the alignments Lincoln discusses in this book genuine or the all too often seeing importance in measurements where there is none? One only need look at the work of Charles Piazzi Smyth to see how you can draw up lines and points and geometry, making it look like there's purpose where there's really just coincidence.
If the churches and castles were built to create a grand geometry, over great distances, only to be seen on a map, to what purpose? The same could be said about such things as the Nazca Lines and figures along with them. Lincoln is confident there is indeed purposeful alignments and spends the majority of the book proving it. To what purpose it was done is where Lincoln speculates and lets the reader know he's dealing in speculation as we just don't know why it was done. If Lincoln's work is right, someone some time ago, used the surrounding natural mountains to then build artificial structures to compliment them and form a "Holy Place", an area not unlike many other grand designs found around the world like the Mounds in the Americas, pyramids in Egypt, temples in Mexico, and so on.
Where I have to admit my limits comes in the math. Mathematics is not my strong spot, let alone surveying and mapping. So I'll have to accept Lincoln's measurements in this book and leave it to better informed to determine if he's seeing alignments that do or don't exist. To his credit, he mentions several times throughout the book cautions of just such problems with work like this and asks the reader to check and double check his work. In any case, if there is purposeful alignments, we need not speculate on ancient astronauts or Atlanteans (Lincoln agrees here) and note that people a long time ago were smart enough to have created such a holy place. What we seem to be constantly discovering is that human beings were smarter than we've given them credit for.
My reasoning for three stars is that the book is very math heavy and perhaps it has to be this way. But I found my eyes glossing over on many occasions and wondered if there was simply a better way to have delivered the information to the reader and put the math in an appendix instead. At any rate, if you want some more solid information on Rennes-le-Chateau than what Lincoln's prior work delivered, this book is it.
