How many workers did it take to build the louvre?

The construction of the Louvre, originally a fortress in the late 12th century and later transformed into a royal palace, involved thousands of workers over several centuries. Estimates suggest that during its major expansion phases, particularly in the 16th and 17th centuries, hundreds to over a thousand workers were employed at any given time, including craftsmen, laborers, and artisans. The exact number varied greatly depending on the specific construction phase and the scale of the project.
