Background photo is a mirrored photo looking over Florence from the Belvedere Franco Zeffirelli

On the left you can just make out the dome of the Cathedral of Santa Maria del Fiore, as well as it's bell tower. On the right you can see the clock tower of the Palazzo Vecchio.

Photo taken on 2015-04-30 (yes I had to dig deep to find this one), the clock tower is just out of view on the left: https://danbooru.donmai.us/media_assets/18647781
