Lutetian limestone (in French, calcaire lutécien, and formerly calcaire grossier) — also known as “Paris stone” — is a variety of limestone particular to the Paris, France, area. It has been a source of wealth as an economic and versatile building material since ancient Roman times (see Mines of Paris) and has contributed markedly to the unique visual appeal of the “City of Light”. It has been hailed as “the warm, elusive, cream-grey stone of the French capital”.^[1]

Its formation dates to the Eocene epoch's Lutetian age, between 47.8 and 41.2 Ma. The name "Lutetian" derives from Lutetia (French, Lutèce) which was the city's name in ancient times.
