Planète guides offers a visit to the old centre with the theme of the European Heritage Days as its theme: living heritage. A look back at the past to discover how buildings and facilities that have become heritage today were key elements of everyday life. A heritage in action to discover! Focus on five strong heritage elements of Grignan: the wash house, the Provençal fountain and the town hall of the nineteenth century, the medieval seigneurial oven and the Porte du Tricot, medieval fortified door transformed into a belfry in the Renaissance. Visitors will discover the golden age of fountains and wash houses - the 19th century-, the water supply program of Grignan and the operation of the village wash house and fountains. The history of the town halls and their development in the nineteenth century, symbol of a republican epic, will be evoked with the comment of the building of the town hall which takes the form of a Roman temple. With the ordinary medieval oven, it is the operation of a seigneurial oven that will be evoked. The fortified gate will allow you to immerse yourself in the functioning of the medieval ramparts but also their evolution over time with the gradual permanent opening of the gates over the centuries. The transformation of this fortified gate into a belfry in the sixteenth century brought the subject of the development of "city" clocks. Departure of the visit: in front of the tourist office of Grignan.
