Question

Le musée du Louvre
why is it du instead of de?​

Answer 1

Napoleon reopened the museum and expanded the collection in 1801, and the museum was renamed Musée Napoléon. "It was Napoleon Bonaparte who created the foundation for the world famous museum the Louvre is today," said Gudek Snajdar.

Answer 2

The use of "du" instead of "de" in this context is due to the fact that the Louvre is a proper noun, and so it is treated differently than other nouns. In French, when a proper noun begins with a vowel or a silent "h," the article "du" is used instead of "de."
