Designed by Salvi and completed by Pannini in 1762, the striking Fontana di Trevi amazes onlookers with its 26.3-metre (86 ft) height and 49.15-metre (161.3 ft) width, making it the largest Baroque fountain in the city and the most famous one in the world. Several movies, including "Roman Holiday" and Fellini's "La Dolce Vita", have certainly contributed to its fame. In 2016, Fendi chose the fountain as the stage of one of its most memorable shows ever, wherein a clear plexiglass runway stretched across the Trevi Fountain.

The building is named after Japanese diplomat Chiune Sugihara, acclaimed for saving the lives of 10,000 Lithuanian, Polish and German Jews during WWII, by issuing Japanese visas for them. The museum exhibits all the important moments of his and the refugees' lives, shedding light on the years of the war as well as its aftermath.
