A round church
L'Eglise de la Sainte Trinite, in French, was built in 1994 and is near Gare Cornavin train station, between it and the United Nations, but in reality it's not on the way to any other tourist attraction in the city. It's on one of the side streets leaving the main Rue de Lausanne and it's rare to see a Roman Catholic church with these features, so it doesn't go unnoticed. It's a giant pink granite sphere 20 meters in diameter with a baptismal water moat around it, making it appear floating. I'll take more photos from the external glass elevator right in front!
