Buried

c. 9500 BCE — Pre-Pottery Neolithic

The world's oldest known megalithic site, predating Stonehenge by 6,000 years. Massive T-shaped pillars carved with animal reliefs were erected by hunter-gatherers before the invention of agriculture, pottery, or metalworking — upending the conventional theory that complex society required farming first.

c. 205-87 BCE — Hellenistic Period

An ancient Greek analog computer used to predict astronomical positions, eclipses, and Olympic game cycles. Its 30+ meshing bronze gears represent a level of technological sophistication not seen again until 14th-century European clockwork. CT scanning has revealed inscriptions suggesting it tracked all five known planets.

c. 500 BCE - 500 CE — Nazca Culture

Hundreds of enormous geoglyphs etched into the desert floor, depicting animals, plants, and geometric shapes visible only from the air. The lines were created by removing reddish pebbles to expose lighter ground beneath. Their purpose remains debated — theories range from astronomical calendars to ritual water-related ceremonies.

196 BCE — Ptolemaic Dynasty

A granodiorite stele inscribed with a decree in three scripts: Ancient Egyptian hieroglyphs, Demotic script, and Ancient Greek. Discovered by French soldiers in 1799, it became the key to deciphering Egyptian hieroglyphs, unlocking 3,000 years of pharaonic history.

c. 210 BCE — Qin Dynasty

An estimated 8,000 life-size clay soldiers, 130 chariots, 670 horses, and 150 cavalry horses buried to protect Emperor Qin Shi Huang in the afterlife. Discovered accidentally by farmers digging a well in 1974, the army represents one of the greatest archaeological discoveries of the 20th century.

c. 1323 BCE — 18th Dynasty

Discovered nearly intact by Howard Carter on November 4, 1922, the tomb of the boy pharaoh Tutankhamun contained over 5,000 artifacts including the iconic gold death mask. It remains the most complete royal Egyptian tomb ever found and sparked worldwide 'Egyptomania.'
