The wrought iron gates with gilded ornaments are the trademark of Place Stanislas. All corners of the square have these gates, so this is the first thing you see when approaching. Wow! The surrounding buildings all are in the same style, as they were carried out within a short period and by the same team.
Place d’Alliance, about 200m eastwards from Place Stanislas, is a whole different experience. It’s a small square surrounded by trees. It looks quite dilapidated, due to a lot of dog shit on the ground and the paint of the monumental Hotel d’Alsace is definitely peeled. The masterpiece here is the fountain that was modelled after the one at Piazza Navona in Rome.
Place de la Carrière is the most classical of the three squares. It lies behind the Arc de Triomphe, on the north side of Place Stanislas. It ends in a semi-circular monument that holds the Palais du Gouvernement.
I visited the squares on foot for about 1.5 hours. I used a walking tour and map that I found at my hotel. There are some other interesting sights underway, like Art Nouveau buildings and an old city gate. It's a nice walk to stretch your legs. The Place Stanislas surely is the major thing to see here.
