Origin and history

The Abbadia Observatory Castle, located in Hendaya (Pyrénées-Atlantiques), is a neo-Gothic building built between 1864 and 1879 on the orders of Antoine d'Abbadie, explorer, astronomer and Basque philanthropist. Designed by Eugène Viollet-le-Duc and Edmond Duthoit, it embodies a unique blend of medieval architecture, orientalism and symbols related to Abbadia's travels to Ethiopia and Egypt. The castle, listed as a Historical Monument and House of Illustrators, houses a pioneer astronomical observatory, a chapel, east-inspired salons, and a library of 11,000 volumes.

Antoine d'Abbadie, born in 1810 of a Basque father and an Irish mother, devoted his life to scientific exploration and the promotion of Basque culture. After twelve years in Abyssinia (1837-1848), he moved to Urrugne and then built Abbadia as an "ideal monument", synthesizing his passions for astronomy, linguistics and art. The castle, left at the Academy of Sciences in 1897, houses Ethiopian frescoes, inscriptions in Basque, Arabic and Latin, and an exotic carved bestiary (crocodiles, snakes, elephants).

The building consists of a central body flanked by three wings: the south wing for receptions (with an Arab living room and a buffalo leather dining room), the east wing for housing (Virginia bedroom and chapel), and the north-west observatory, equipped with a decimal meridian bezel unique in the world. Local materials (Béhobie limestone, pink and black bellows) and Basque labour reflect the regional anchoring of the project. Viollet-le-Duc and Duthoit collaborated closely, integrating Gothic, Moorish and Ethiopian elements, such as Maréchal stained glass windows or Parvillé ceramics.

The 415-hectare estate, now partially managed by the Conservatoire du littoral, includes a landscape park designed by Eugène Bühler, a conservation orchard of ancient fruit varieties, and cliffs classified as ZNIEFF. Abbadia also symbolizes Abbadie's commitment to the Basque language: he organized traditional festivals, financed poetry competitions, and campaigned for the preservation of the euskara. His scientific heritage continued through the Observatory, which was active until 1975, and the Antoine d'Abbadie Prize for Astronomy.

Ranked a historic monument in 1984, the castle benefited from a major restoration (1997-2008) and now hosts visits, artist residences and an escape game about the life of Abbadie. The chapel, where Antoine and Virginia lie, and the library (with its engraved Basque maxims) bear witness to their dual heritage: scientific and cultural. The site, labeled Maison des Illustres in 2012, remains a place of memory and research, between architectural and natural heritage.
