They almost run a dead heat. The Pyramid of Giza is generally thought to have been built around 3200 BCE while Stonehenge is thought to have been constructed about 3100 BCD, which would make the pyramid older by just 100 years. Those figures are only estimates.
Stonehenge was created between 2600BCE and 2400BCE. It is the most famous henge, but there are older ones in the surrounding areas. Egyptian pyramids were created between 2700BCE and 1700BCE with the Great Pyramid of Giza being completed in 2570 after 10-20 years of construction. So the ages are pretty close!
