From 1930 to 1985, Elvire Popesco lived in a villa in Mézy-sur-Seine, Yvelines. The villa, designed by Robert Mallet-Stevens for fashion designer Paul Poiret was acquired by Popesco and remodeled in 1932 by architect Paul Boyer. It was declared a historic monument in 1984, but it has since decayed. Bought for 1.8 million French francs in 1999, it is opened occasionally to the public. It has been used as location for movies like Holy Motors.
