Gaius Cluilius

Gaius Cluilius was the king of Alba Longa during the reign of the Roman king Tullus Hostilius in the middle of the seventh century BC. Alba Longa was an ancient city of Latium in central Italy southeast of Rome.

He constructed the Cluilian trench, sometimes referred to as the "Cluilian ditches", which was a huge warfare trench that surrounded the ancient city of Rome approximately four to five miles outside the city walls. It was built for trench warfare and was used in various wars and battles for centuries after the original construction for this very purpose.

Gaius Cluilius was played by Andrea Aureli in the 1961 film Duel of Champions.
