BBC - How to Build a Cathedral (2008)

Posted By: Tutorial

Date: 16 Oct 2016 12:01:03

The great cathedrals were the wonders of the Medieval World - the tallest buildings since the pyramids and the showpieces of Medieval Christianity. Yet they were built at a time when most of us lived in hovels. Architectural historian Jon Cannon explores who were the people that built them and how were they able to achieve such a bold vision.
