A nasone (plural nasoni), also called a fontanella (plural fontanelle, lit. "little fountains"), is a type of drinking fountain found in Rome, Italy. Literally meaning "large nose", they got their name from their characteristic design first introduced in the 1870s. There are approximately 2,500–2,800 nasoni in Rome, supplying people with free drinking water.

Sampietrini (also sanpietrini) is the typical kind of pavement found in the historic district of Rome and in St. Peter's Square, Vatican City. The earliest examples were made by trimming large blocks that had been used in ancient Roman roads, recently discovered in fifteenth- and sixteenth-century archaeological excavations. The first documented use in Rome of "sampietrini" stones was during the reign of Pope Pius V (1566–72). Over the next two centuries the stones were used to pave all the main streets of Rome, because this mode was superior to brick, for example by providing a smoother and stronger surface for carriages, among other reasons.
