Tullins is a city steeped in history, of which the architecture of the town center bears witness. From the beginning of the XNUMXth century, industrialization developed in the hamlet of Fures with hemp linen, silk, metallurgy and stationery thanks to the driving force of water. After the damming up of the Isère at the end of the XNUMXth century, the plain of Tullins then lends itself to agriculture. The production of walnuts, a fruit originating from the Orient, developed to replace the vineyards decimated by the phylloxera crisis.
Since then, you have been in the geographical area of ​​the Grenoble Walnut Protected Designation of Origin set up in 1938. Three varieties of walnuts are included: the Franquette, the Mayette and the Parisienne. Nut producers are called nuciculturists. Farms are present all along the route and offer nuts, walnut oil, vegetables, cheeses or livestock products.

Additional information Shops in the town center. Feel free to stroll through the old town of Tullins or take a break in the pretty Clos des Chartreux park. If you are on a bike, plan to climb a few steps at park level or go around by road.
