Born in Saint Petersburg (Russia) in 1901, Prince Peter Wolkonsky discovered his passion for botany as a child by secretly invading the vegetable garden of the Tsar who resided in the neighboring palace. He spent the first part of his life painting plants and landscapes on a grand tour that took him from North Africa to Provence via Italy. He then moved to the Paris region where he designed his first garden. In 1965, he discovered Le Verger, which later became Kerdalo, an old farm overlooking the Jaudy river and opposite the old town of Tréguier. A visionary, he was already aware of the importance of water in the development of his garden and chose to settle on hilly land over which several springs bubble. By taming them, he imagined a garden with ponds, waterfalls, water stairs, an Italian grotto and pavilions decorated with shells. He visualizes in his mind associations of colors and textures that evolve over the seasons. More than 5,000 plants find their place in these 17 hectares. When he died in 1997, Kerdalo was taken over by his daughter Isabelle and her husband Timothy. Source: https://lesjardinsdekerdalo.com/?page_id=52

Beautiful circular path along the river. Long leg clothing is an advantage, some nettles and thorns along the path.

The Kerdalo gardens are the fruit of the imagination of Prince Peter Wolkonsky, born in Russia at the beginning of the last century. Passionate about botany, in 1965 he discovered the place called Le Verger which would become Kerdalo. This old farm, magnificent on its promontory overlooking the Jaudy river, faces the old town of Tréguier. Today, the gardens are managed by the prince's descendants. It is open to the public from April to September.

An ancient city known and recognized for its religious influence, Tréguier stands on the balcony of a hill overlooking the estuary formed by the meeting of the Jaudy (coming from the south) and the Gaudy (coming from the east). The port, popular with boaters, benefits from deep waters which accommodate large vessels. Its city center, dressed in countless colors and old stones, is organized around the Saint-Tugdual Cathedral. Considered one of the most beautiful religious buildings in Brittany, it stands out as a must-see in the city. The town, crossed by the GR 34, is a major stopover for itinerant hikers. Many shops and services allow you to get organized.

This is one of the luckiest. This mill has been the subject of a magnificent restoration project.
