In the #PBS series "Nova," there's an episode about how France is rebuilding the #NotreDameCathedral. It said that the original North Rose Window design had the circular design turned a bit on its side, in order to increase its structural integrity.

The show (full episode in link) was a fascinating episode about the craftsmen and detailed work involved in resurrecting the iconic fire-damaged church.
