Non-existent in prehistoric times, a small town in the Gallo-Roman era, a large village during the Middle Ages, and a small city in modern times, Grenoble has developed quickly, finally winning fame and glory in the 20th century. This perhaps explains why it is so often said that Grenoble is a city with no history, and certainly no heritage. Nothing could be further from the truth ! We must therefore take a closer look at this city, explore it and give free reign to our curiosity. If we do so, we will discover that it is a beautiful city, and that we can also love it for its heritage.
