Court, Joseph-Désiré – Mariage de Léopold Ier et de la princesse Louise d’Orléans au château de Compiègne, 9 août 1832 Château de Versailles

The picture has something of this: people, group, many, ceremony, indoors, man, church, crowd, woman, room, chandelier, wear, god, castle, priest, prayer, city.
Perhaps it’s a painting of a large group of people standing in a room with a chandelier and a chandelier in the middle of the room.
