The Pyramid of Giza and the Colosseum were built by two different ancient civilizations.
The Pyramid of Giza is located in Giza, Egypt, and was built by the Ancient Egyptian workers during the reign of Khufu. The Pyramid of Giza was constructed as a burial sight to house deceased Pharaohs. It is suspected to have been built from roughly 2550 to 2490 BC.
The Colosseum is located in Rome, Italy, and was built by Ancient Roman slaves under the command of Emperor Vespian. The Colosseum was an amphitheater, used as a way for Ancient Romans to provide large scale entertainment, such as hosting games, dramas, gladiator fights, and even public executions. It was built in 70 AD.
These two wonders of the world are different because they were built in two different countries by two drastically different civilizations during separate time periods. They were constructed with different purposes in mind, one being for entertainment, and the other being for housing the dead/a final resting sport for those who ruled over Egypt.
