The nave soars to 385 feet! The glass is old and splendid, like at Chartres. And there was evidence of damage from the French Revolution
I left the cathedral, and went to the cathedral museum. The museum teaches you all aspects of the cathedral, how it's contructed, why you build one, the different trades involved, and the different aspects of symbolism involved.
There were three short films of stone carvers that were mesmerizing. Wow! Mind boggling. The years of training and time and effort involved. The sound of the chink, chink, chink took me back to Malabarpurim (spelling?), in India.
