Potager du château de la Roche-Guyon, French kitchen garden at Château de la Roche-Guyon, France

The Potager du château de la Roche-Guyon is a vegetable garden laid out in four large square sections, each divided into triangular plots. Water basins positioned at the center of each section provide irrigation for the plants grown throughout the garden.

Created in the 17th century at the initiative of Madeleine Le Tellier de Louvois (1665-1735), wife of François VIII de La Rochefoucauld, first Duke of La Roche-Guyon, the kitchen garden was reworked around 1741 by their son Alexandre, second duke. After the Revolution the principle of a useful garden faded; an independent market garden worked the plot until cultivation was abandoned around 1955. Restored on its original plan by architect Pierre-André Lablaude over three years, it reopened on 5 June 2004.

The garden reflects French market gardening traditions through its organized layout and practical design for growing food. You can observe how the symmetrical beds and water features support the daily work of the gardeners tending the land.

The garden lies flat between the castle and the Seine, enclosed by walls, with two groves sheltering it east and west. Entry is free during the castle's opening hours. Guided tours and workshops are held in the garden, and since 2013 all its produce and derived products are certified organic.

The garden's 2004 restoration cost 1.4 million euros and took three years, led by chief heritage architect Pierre-André Lablaude. For the first season, before planting was complete, each of the four squares hosted an exhibition on one of the four elements — air, earth, water and fire — with imaginary flowers and vegetables.
