What are the gargoyles of notre dame made out of ?

• I need to find the history of the gargoyles of notre dame and i can't find what it is built out of. Please help!!

• Answer:

  This is a difficult one... my best guess is limestone. A lot of old statues were made of limestone because of its resistance to weathering. Here's a quote from a page on the history of gargoyles; "Certain types of limestone of the Seine basin, like Liais-cliquard, lent themselves marvellously to the sculpture of these long pieces of stone that project over the constructions. A firm, resistant material was necessary for these conditions to inhibit all causes of destruction. It is also in Paris or in the country where Liais are found, like in Tonnerre for example, where we can see the most beautiful gargoyles. Furthermore, the Paris sculpture school in the Middle Ages is clearly superior to those of neighbouring provinces, especially in statuary. Gargoyles were used systematically in Paris around 1240 ; it is at Notre Dame that we see some gargoyles appear on the upper cornices rebuilt around 1225. They are short, robust but already sculpted by skilled hands."
