The Great Pyramid of Khufu is renowned for its extraordinarily precisealignment to true north. Modern surveys show that its sides deviate from the cardinal directions by only a few arc minutes, making it one of the most accurately oriented structures ever built.

For more than four thousand years, few man-made constructions have matched this level of precision. The achievement is especially remarkable because the builders had no compasses, satellites, or modern measuring instruments.

Many researchers believe that Egyptian surveyors determined north by observing the positions of circumpolar stars and tracking their movements across the night sky. Others suggest the use of solar observations combined with careful geometric methods. Whether by stellar or solar techniques, the accuracy of the alignment remains one of the most impressive accomplishments of ancient engineering. Although it seems astonishing today, most archaeologists consider such precision entirely possible with the knowledge and observational skills available at the time.

The Great Pyramid of Khufu is aligned with the four cardinal directions (north, south, east, and west) with an extraordinary level of precision, deviating from true north by only about four arcminutes (roughly 0.05 degrees). This alignment features a slight, consistent counterclockwise rotation.
