National Geographic 3D puzzle of the Colosseum is a combination of puzzling and building. The end result is a sturdy building, without having to use glue. The Colosseum was the largest amphitheater (round theater) in the Roman Empire. Partly because of that it had many uses: for sporting events, fights with wild animals and of course the famous gladiator fights. The construction of this amphitheater is estimated to have taken about eight years. Hopefully you can do it faster at home! Consists of 131 pieces. Comes in a full-color box. Suitable for children from 10 years.
