Origin and history

Costaéres Castle, although often referred to as a castle, is in reality a neo-medieval style mansion typical of secondary residences built at the end of the 19th century on the Pink Granite Coast. Built in pink granite from the quarries of La Clarté (Perros-Guirec), it is distinguished by a complex architecture, the result of several enlargements, and a slate roof. Its interior was built with the wood of a three-mast failed in 1896, Mauritius, adding a maritime historic touch to its construction.

The island of Costaéres, bought in 1892 by Polish engineer Bruno Abakanowicz for 0.25 francs per square metre, initially housed potato crops and fish dryers. The mansion was completed around 1896 under the direction of engineer Lanmoniez and contractor Pierre Le Tensorer. After Abakanowicz's death in 1900, his daughter Sofia added a western wing. During World War II, the site was requisitioned by the German army, suffering internal damage.

A fire in 1990 following roof work partially damaged the interior. A tourist symbol, the castle often illustrates the postcards of the region. Recently, it served as a stage for the series La Maison (2024) and has been owned since 1988 by German actor Dieter Hallervorden. Available in 2025 for 9.5 million euros, it embodies both an architectural heritage and a page of local history.

The island, accessible at low tide from the beach of Tourony, derives its name from the Breton kozh-sec-herezh ("old dryer"), recalling its past use by fishermen. Ranked in Natura 2000 area, it faces the beaches of Saint-Guirec and Ploumanac Several personalities stayed there, including writer Henryk Sienkiewicz, who wrote Quo vadis ? ( Nobel Prize 1905), or singer Léo Ferré.

The site thus combines industrial history (granite careers), literary heritage, and tourist attraction, while bearing traces of the conflicts of the twentieth century and climatic hazards. Its eclectic architecture and its unusual location make it a unique monument in the Breton landscape.
