The Great Pyramids of Giza were built around 2560 BCE during Egypt’s Old Kingdom. The Viking Age, by contrast, began in the late 8th century CE—roughly 3,300 years later. There is no overlap; the pyramids were already ancient monuments when the first Norse longships set sail.
This staggering time gap underscores the immense depth of human history: the pyramids were constructed when woolly mammoths still roamed parts of Siberia, while the Vikings emerged in a world already shaped by classical antiquity, the rise of Islam, and the early Middle Ages.
