The Tower of Eben-Ezer is a self-built castle constructed in the 1960s by a single man in the isolated Jeker valley of Belgium. The builder, Robert Garcet, was fascinated with the Bible, numerology and ancient civilizations. The entire seven-level tower is built of flint, and according to Garcet, was designed using ancient mystical measurements. On the top of the tower are four giant biblical animals, and the interior is full of Garcet's biblical, archaeological, paleontological and geological art.

Even more curious is that although the tower only looks ancient, it sits on top of a vast network of truly ancient tunnels. Garcet claims to have discovered over a hundred "new" fossilized creatures and a 70-million year-old village in the labyrinth of tunnels under the tower! Unfortunately, the village was destroyed by a mining explosion before it could be studied.

A new educational space called the Geospadium takes the visitor on a tour of the history and use of the flint stone.

Join us on Obscura Day - March 20th, 2010 - on an expedition leaving from Brussels to tour the Tower of Eben-Ezer and marvel at this seven-level castle built by hand in the 1960s.
