Top 7 Most Amazing Man Made Wonders

Colosseum, Italy

One of the most famous man made wonders in Rome dates back to the high point of the Roman Empire and has a well known and rather bloody history. It was built as a stadium to stage show fights – often between slaves, animals, and convicts while people cheered for their favourite contenders. Most of the fights ended with one of the gladiators dying and the victor was spared to fight another day. There were many mechanisms to make the fight attractive for the spectators including trap doors to release animals from underground and flood the arena to stage sea battles.
