The latest addition to the storied grounds of Château La Coste outside of Aix-en-Provence, a curvaceous white pavilion designed by Brazilian architect Oscar Niemeyer, will be inaugurated on April 8 and opens to the public in June. Conceived in the architect’s last years and constructed posthumously, the pavilion is the final project drawn by the Pritzker laureate before his death, at 104, in 2012. It is also, says the museum, his “last gift to France”—the country where he went into exile in 1967 following the Brazilian military coup, and where he built numerous projects such as the French Communist Party headquarters and the Bourse du Travail in Bobigny.
