It’s not the first fire in Notre-Dame some of the Rose windows have not survived past fires. It’s amazing the structural strength of these great buildings and their architectural contribution.
Another great European building Mezquita de Córdoba
Known locally as Mezquita-Catedral, the Great Mosque of Cordoba is one of the oldest structures still standing from the time Muslims ruled Al-Andalus (Muslim Iberia including most of Spain, Portugal, and a small section of Southern France) in the late 8th century. Cordoba is a two hour train ride south of Madrid, and draws visitors from all over the world.
These great buildings a glue that keeps social fabric together.
