From the Romans to the Raj, the Ottomans to the Incas, great empires have come and gone through the ages; but all have left behind extraordinary monuments, inventions and innovations that changed the course of history. The six-part series EMPIRE BUILDERS covers the rise and fall of five great empires and the remaining monuments that symbolize the enduring achievements of these global powers. Each episode visits 10 significant sites, exploring how they were built, for what purpose, and what they reveal about the empire's place in history. Expert contributors and CGI recreations help create a vision of life as part of the empire and the ongoing legacies that affect today's modern world.
