When the Musée Ariana was bequeathed to the City of Geneva in 1890, a total of 118 stained-glass windows had been acquired under the authority of Gustave Revilliod (1817-1890). Today, our institution has over 400 pieces, dating from the 12th to the 21st century. The 5th part of the series “L’Ariana sort de ses réserves” (the Ariana Comes Out of its Reserves) highlights a selection of this exceptional heritage.
