You can pass by here without noticing this 18th century building which has no particular architectural interest, because its interest is not visual, but audio ... Indeed, this castle houses a legendary recording studio which had its heyday in the 70s and 80s. Founded in 1969 by Michel Magne, a key composer of film music from the 60s/70s (he notably composed the music for Tontons flingueurs, Angélique, Fantomas and OSS 117), the castle offered for the first time at the time a residential studio offering room and board to artists who could thus take the time to record their album in the heart of the peaceful countryside of the French Vexin. Its notoriety would go so far as to attract the big names of Anglo-Saxon rock. David Bowie, Elton John, Pink Floyd, Jacques Higelin, Iggy Pop, The Bee Gees, Claude Nougaro, Eddy Mitchell, Cat Stevens, T Rex, Fleetwood Mac, Marvin Gaye, Bernard Lavilliers, and many others recorded here. This story is told in various books and articles, including: "Herouville, the Haunted Castle of Rock," a book by Laurent Jaoui "The Lovers of Herouville," a graphic novel by Yann le Quellec and Romain Ronzeau "Herouville Castle, a French Rock Madness," a documentary by Christophe Tale https://www.lemonde.fr/culture/article/2025/02/07/le-chateau-d-herouville-une-folie-rock-francaise-sur-france-5-la-fascinante-histoire-d-une-pure-utopia-des-annees-1970_6536323_3246.html
