Strasbourg est bien connue pour ses bordures de trottoirs ou ses quais de la gare en granite, mais quelques autres exemples illustrent bien les roches environnantes et l’histoire de la r\u00e9gion. L’itin\u00e9raire de cette sortie est retrac\u00e9e sur le plan<\/a> par la chronologie des num\u00e9ros. Ce r\u00e9sum\u00e9 montre diff\u00e9rentes familles de roches (r\u00e9capitul\u00e9es dans le tableau)<\/p>\n\n\n\n

…\u00e0 chacun de d\u00e9cliner la sortie selon son envie!<\/p>\n\n\n\n
