Costaérès Castle (French: Château de Costaérès, Breton: Kastell Kostaerez) is a neo-Gothic manor house built in the 1890s. It was commissioned by the Lithuanian-Polish mathematician, electrical engineer, and inventor Bruno Abdank-Abakanowicz on a previously uninhabited island of the same name. Because of its magnificent architectural design, it is also referred to as a castle (French: château).

The island with the castle is located in the Côtes-d'Armor department in Brittany, France, off the Côte de Granit Rose. Administratively, the manor house belongs to the municipality of Ploumanac'h, but is still located within the municipality of Trégastel.

In 1988, the German comedian and actor Dieter Hallervorden purchased the property and had it converted into a second home.

The Château de Costaérès, located on a rocky islet off the Pink Granite Coast in Brittany, is a true jewel in the middle of the waters. This castle, surrounded by maritime pines and rocks sculpted by the sea, offers a breathtaking landscape, particularly at high tide when the island seems to float on the water. Accessible only at low tide or by boat, this mysterious place attracts visitors for its wild beauty and enchanting setting.

The neo-Gothic castle, with its towers and battlements, was built in the early 20th century. Although the island is private and the castle is off-limits, it is clearly visible from hiking trails such as the Sentier des Douaniers or from the water. Over the years, it has served as a summer residence and meeting place for artists and celebrities.
