The Arc Héré is a triumphal arch that closes the northern end of Place Stanislas, forming the gateway between the 18th-century new town and the older formal gardens of Place de la Carrière. Built between 1752 and 1756, it is a strikingly elegant structure, slender and light compared to Roman triumphal arches — more gateway than monument.
The arch is named for Emmanuel Héré de Corny, the architect who designed the entire Place Stanislas ensemble. Walk through it to reach the long, tree-lined Place de la Carrière, which leads in turn to the Palais du Gouvernement — the combined sequence of three spaces is one of the great set pieces of French urban planning. The arc itself is best appreciated from the Place Stanislas side, framed by Lamour's gilded gates.
