The city known to have the most fountains in the world, while also employing bacteria to preserve them, is the city of Rome in Italy.

The city of Rome has an estimated 2000 water fountains. During the times of ancient Rome, these fountains played a crucial role in the sustainability of the city, given that they were the only source of public potable water available. Private drinking water was a luxury reserved for the wealthy.

Currently, some scientists in Rome are employing the use of bacteria to aid in preserving these mounuments. They use enzymes to draw out the bacteria deep inside some marble blocks, then allow it to calcify on the surface, thus adding structural strength to the stone. They are also using specialized strains of bacteria to eat away at grease and grime on some of the fountains.
