Ancient Maya Metropolis (2022)

The ancient ancestors of today’s Maya people thrived in large sophisticated cities across Central America for centuries. Why, around 750 CE, did they begin to abandon many of their major cities? Archaeologists investigate dramatic new evidence of the catastrophic droughts and instability that pushed cities beyond their limits. The evidence also testifies to the survival and resilience of the Maya people, whose traditions and creativity continue to enrich the world today.

Ancient Builders of the Amazon (2023)

Recent discoveries in archaeology are exploding the myth of the Amazon as a primeval wilderness, revealing traces of ancient civilizations that flourished for centuries, with populations numbering in the millions.

Decoding the Great Pyramid (2019)

How did the Egyptians engineer the Great Pyramid of Giza so precisely, and who were the thousands of laborers who raised the stones? Stunning new archaeological evidence—including the recently uncovered logbook of a labor team leader—provides new insights into these age-old questions. NOVA delves into these construction secrets to trace how mobilizing labor and resources on such a massive scale transformed ancient Egypt.

Secrets of the Forbidden City (2017)

The Forbidden City is the world’s biggest and most extravagant palace complex ever built. For five centuries, it was the power center of imperial China and survived wars, revolution, fires, and earthquakes. How did the Ming Emperor’s workforce construct its sprawling array of nearly 1,000 buildings and dozens of temples in a little over a decade?

Hagia Sophia: Istanbul's Ancient Mystery (2015)

Whether serving as Christian church, Islamic mosque, or secular museum, Hagia Sophia and its soaring dome have inspired reverence and awe. For 800 years, it was the largest enclosed building in the world—the Statue of Liberty can fit beneath its dome with room to spare. How has it survived its location on one of the world's most active seismic faults, which has inflicted a dozen devastating earthquakes since it was built in 537? As Istanbul braces for the next big quake, a team of architects and engineers is urgently investigating Hagia Sophia's seismic secrets. Follow engineers as they build a massive 8-ton model of the building's core structure, place it on a motorized shake table, and hit it with a series of simulated quakes, pushing it to collapse—a fate that the team is determined to avoid with the real building.

Petra: Lost City of Stone (2015)

In a daring experiment, an archaeologist and sculptors team up to carve an iconic temple-tomb to find out how the ancient people of Petra built their city of stone. Meanwhile, scientists using remote sensors and hydraulic flumes uncover the vast city and its sophisticated water system. The race is on to discover how these nomads created an oasis of culture in one of the harshest climates on Earth.

Colosseum: Roman Death Trap (2015)

One of the ancient world's most iconic buildings, the Colosseum is a monument to Roman imperial power and cruelty. Its graceful lines and harmonious proportions concealed a highly efficient design and advanced construction methods that made hundreds of arches out of 100,000 tons of stone. In its elliptical arena, tens of thousands of gladiators, slaves, prisoners, and wild animals met their deaths. Ancient texts report lions and elephants emerging from beneath the floor, as if by magic, to ravage gladiators and people condemned to death. Then, just as quickly, the Colosseum could be flooded with so much water that ships could engage in sea battles to the delight of the crowd. Now, archaeologists and engineers are teaming up to recreate a 25-foot lifting machine and trap door system capable of releasing a wolf into the Colosseum's arena for the first time in 1,500 years. Do they have what it takes to replicate the innovation and ingenuity of the Romans? 

Emperor's Ghost Army (2014)

In central China, a vast underground mausoleum conceals a life-size terracotta army of cavalry, infantry, horses, chariots, weapons, administrators, acrobats, and musicians, all built to serve China's first emperor, Qin Shi Huang Di, in the afterlife. Lost and forgotten for over 2,200 years, this clay army, 8,000-strong, stands poised to help the First Emperor rule again beyond the grave. Now, a new archaeological campaign is probing the thousands of figures entombed in the mausoleum. With exclusive access to pioneering research, "Emperor's Ghost Army" explores how the Emperor directed the manufacture of the tens of thousands of bronze weapons carried by the clay soldiers. NOVA tests the power of these weapons with high-action experiments and reports on revolutionary 3D computer modeling techniques that are providing new insights into how the clay figures were made, revealing in the process the secrets of one of archaeology's greatest discoveries.
