Welcome to Place Broglie, one of the main squares of Strasbourg. You are on the Grande Île, the ancient island heart of the city. Locals know the square in Alsatian German as Bröjel. Look along its shape first. It is a long, elongated rectangle, about 275 meters from end to end and only about 50 meters wide, so it feels more like a grand open avenue than a typical square. The buildings around it read like a roll call of civic power: the Opera House, the City Hall, the Governor's Palace, the Prefect's Palace, the Strasbourg building of the Banque de France, and the historic officers' mess. Over the next few stops, we will go back to the medieval market, look at the cannons on a famous façade, hear how a war song was born nearby, and follow the square through speeches, monuments and Christmas lights. Let's start walking.
