South America's 'Megalithic Age' is evidenced by the great antiquity and different styles of ancient architecture found across Peru and Bolivia, particularly throughout the region defined by the Andes mountain range. It has also been written about by many authors and researchers for centuries. 

Sir Clements Markham was one such author, he travelled and studied the region, and it's history for more than 60 years, was an expert in the Quecha language, and intimately familiar with all the primary sources of information, scant though they are, given the conquest of the new world by the Spanish invaders. His conclusions after a lifetime of research are very interesting, particularly when compared to those of our current academic establishment.

A small correction: at 37:52, the label should read 'Chavin Temple' and not 'Sacsayhuaman' . A small oversight that I missed in editing.
