Architect: Jean Courtonne
Interior Architect: Antoine Mazin
Courtonne completed the structure and exterior facades before the new owner replaced him with Antoine Mazin. The new architect erected the porch and the “iconic double doors [which] open onto the semicircle court of honor.”
During WWI the hotel ended up in the possession of the enemy. But in 1922 France bought back the property thanks to the Treaty of Versailles. It is now the home of the Prime Minister.
