Designed and built in 1933 by the architects Pol Abraham and Henry Jacques Le Même, this sanitorium was for women only. Reconverted into a holiday centre it is classified as 20th century heritage.
A real light catcher, it is distinguished by its "split" plan, with a huge central building, four pavilions and a tiered layout. Its wooded park was designed by the landscape architect René Edouard André. The décor of the chapel, painted a fresco by Angel Zarraga, unfolds like a film that revolves around the visitor.
