Description
This ingenious representation of a classic design allows the builder to discover the principle of the keystone and its function in the support of an arch. This is an excellent example how bridges and other structures were built 2000 years ago.
Contents
- 24 blocks to construct the wall.
- Base Template and Stand
- 9 arch blocks
- Crane to construct the arch
The blocks are all constructed from solid beechwood with a natural finish for the Child to focus on the precise construction of the arch. This also provides a control of error so that there is a specific place for each block.

Previously I bought a cheaper Roman Arch. The blocks were not accurate. This one from childrens house montessori materials is really good, because the lever slides out smoothly and the arch is solid once constructed. Really happy with my purchase.
