Several scientific discoveries have been named after Lutetia. The element lutetium was named in honor of its discovery in a Paris laboratory, and the characteristic building material of the city of Paris,Lutetian Limestone, derives from the ancient name. The "Lutetian" is, in the geologic timescale, a stage or age in the Eocene Epoch. The asteroid 21 Lutetia, discovered in 1852 by Hermann Goldschmidt, is named after the city.
