During my walk around Belgium in favour of Street nurses asbl In June, I was unable to visit this monument because it was some 4 km off my route. Walking around for eight kilometres with a heavy backpack is just a bit too much....
During my cycling trip around Belgium for the Braille League asbl this did succeed, and I am not at all sad about it! When I finally reached the silex tower after some GPS wanderings, I immediately felt a positive energy emanating from it.
The two ladies at the reception desk were extremely friendly and told me enthusiastically about 'their' tower and its maker. I was even allowed inside at a reduced rate because I was cycling for charity.
Here is a word about Robert Garcet and his tower that I distilled mainly from the concise visitor's guide. Then you will already not have to read it in its entirety on any visit.
Robert Garcet (1912 - 2001) was a stonemason by profession. He preferred working with flint (silex) and moved to the Jeker valley near Eben-Emael in the early 1930s because this rock was plentiful there.
In 1940, the Germans invaded Belgium after taking out the 'impregnable' underground fortress of Eben-Emael in no time (a day and a half according to Wikipedia). Garcet was shocked by the war and decided after the war to build a peace monument on the spot where the war began.
Garcet was a self-taught artist, architect, writer-philosopher and mystic. He drew inspiration for his creations from biblical texts: 'Eben-Ezer' is the name of a location where the prophet Samuel placed a memorial stone after the Israelites defeated the Philistines. It means 'Stone of Salvation' or Help Stone.
Construction of the tower lasted from 1948 to 1963. Garcet built it with his closest friends. It symbolises friendship, brotherhood and peace.
In the structure of the building, the numbers four, seven and twelve recur regularly: the four sides of the square tower measure 12 metres each; the tower, including the underground floor, consists of seven floors connected by seven and twelve steps each. Garcet based this on his own number symbolism, but I did not have enough time to read more about it.
The basement floor extends against the level of groundwater and the above-ground part of the tower, measured to the top of the wings of the four large cherubs adorning the roof, is 33 metres high (according to the visitors' brochure, Wikipedia lists different dimensions that are, however, in my opinion too low for a building with six above-ground floors). Although Garcet was not religious, he saw the tower as a connection between earth and heaven.
Inside, unfortunately, I was not allowed to take photos. In a nutshell, the six upper floors deal with the following themes:
1) Robert Garcet's thoughts, contained in these six pacifist and humanist values: 'loving - thinking - creating - freedom - equality - fraternity. You can read them left and right next to the entrance (see photo).
2) The cherub hall: There stands 'the beast', a dragon-like dinosaur that symbolises human stupidity and wariness. It is surrounded with war symbols and has large hind legs and small forelegs: it can flatten and destroy much, but build nothing. In the corners are the four horsemen of Revelation: Cyrus, who expanded the smaller ancient Persian into the Persian empire, the world empire that the second horseman, the later Alexander The Great, would conquer after a series of bloody wars after tying the Gordian knot. The third horseman is Caesar Augustus with a pair of scales in his hands: justice, a balance that, because of two weights and measures, never reaches equilibrium. The last and fourth rider is Constantine the Great with a bishop on the back of his horse: Constantine made Catholicism the dominant state religion, and that also led to a serious dose of violence throughout history. Around that pair, Garcet drew crosses and gallows with roots: instruments of death that cannot be overthrown because to this day city people are still being persecuted and killed for being different, believing different or thinking different...
3) On the third level, you will find the bookstore and information on the background and origins of Garcet's writings.
4) Private, closed to the public
5) An esoteric interpretation of revelation and Garcet's theories on the origin of man. The people of the 'Ancient People' were artists who worked flints as early as their formative years. Garcet studied the stones and fossils he found in quarries and called them 'figure stones' and 'thought stones'.
6) Here you will discover the chalk era and Garcet's vision of the 'Great Unity of the Living', which he derived from the existence of the chalk sea of which he found traces in these parts.
7) On the roof are the four giant cherubs: bull, lion, human/sfynx and eagle. They resist the destructive elements and are messengers of all dreams of a better world. On the battlements and side walls are signs of a universal esoterism.

If you want to thoroughly visit Robert Garcet's flint museum and his vision of the world and humanity, set aside at least several hours for it. Two hours won't do it. Definitely worthwhile for thinkers and meaning seekers. Garcet did not think only on the cognitive level, which makes him just as interesting. And difficult.
