An arch named after Stanislas' famous architect, Emmanuel Héré, disciple of Boffrand. He entered Stanislas service when he was 20 years-old! Here we can see a Corinthian arch crowned by a medallion (a Genie holding king of France Louis XV’s portrait and an Allegory of Lorraine).
Top of that, the allegory of Fame with a trumpet: Hostium terror, Foederum cultor, Gentisque decus et amor which means “Enemies terror, treaties instigator, glory and love of the people”.
We also can see 3 low-reliefs made of white marble: Mercury and Minerva, Apollo and Muses, Apollo against a dragon with the device Principi pacifico. On the cornice, Ceres, Minerva, Hercules, Mars. The arch was dedicated to Louis XV: hey, he was Stanislas’ son-in-law!
