Origin and history

The Château de Granville, located in Port-Saint-Père in Loire-Atlantique, is a neo-Palladian villa built between 1820 and 1825 by the French architect Étienne Jean-Baptiste Blon. Sponsored by Aristide Locquet de Grandville, mayor of the commune and politician, this castle is inspired by the Venetian villas of Andrea Palladio, with a central plan and a facade decorated with ionic loggias. Its architecture reflects the 19th century's passion for palladianism, mixing classical purity and harmony with nature.

The estate includes outbuildings organized in "U" (farm, vegetable garden, washhouse) and a neogothic chapel added in 1844 by architect Théodore Nau. The park, designed in 1851 by landscape architect Jean-Dominique Noisette, adopts a picturesque "English" style, with winding alleys and carefully chosen vegetation to imitate wild nature. This park, partially preserved today, highlights the castle overlooking the marshes of the Acheneau.

The building of the castle was marked by a financial dispute between Aristide de Grandville and Blon, resolved after 23 years of proceedings. On the death of its sponsor, the estate passed by successive alliances to the Moulin de Rochefort families, Dampierre, and then to Argenlieu, who are now restoring it. Ranked a historic monument in 1992, the castle illustrates the influence of Italian models in France and the evolution of gardens from the 18th to the 19th century.

The architecture of the castle is distinguished by its symmetry and Palladian elements: central forebody, paired ionic columns, and two-sided slate roof. The facade on the garden side, more decorated, contrasts with that on the courtyard side, covered with a grey coating typical of the Nantes Country. The outbuildings, in shale and granite, adopt a sober style, while the neo-Gothic chapel adds a medieval touch to the estate.

The Parc du Château de Granville, designed to « stage the landscape », combines local species (sapins, pines) and curved lines inherited from the russeau movement. Although some alleys disappeared before 1943, Jean-Dominique Noisette's original plan remains visible, preserving the romantic spirit of the garden. This site thus embodies the ideal 19th century: the alliance between classical architecture and domesticated nature.
