One of the notable landmarks of Rimini, a charming city in Italy, is the "Rainforest" Fountain. This historical fountain, also widely known as the Pinecone Fountain (Fontana della Pigna), adorns the central Piazza Cavour and attracts attention with its unusual design.

The structure is a complex composition of three circular basins that decrease in size toward the center. The fountain is crowned by a drum with a sculpture in the shape of a pinecone—it is this detail that gave the fountain its Italian name "Pigna." Each of the basins has an original shape resembling overlapping circles, which gives the entire ensemble a special refinement and makes it one of the main points of attraction in the spacious central square of Rimini.
Curiously, some see a resemblance in the shape of the central part of the fountain not so much to a conifer cone as to a large boiled egg in a special cup. Although the water pressure may not seem particularly powerful, the water from the fountain is potable. This is possible because the fountain is fed by an ancient aqueduct that delivers pure water from remote karst springs. Thus, the "Rainforest" Fountain is not only a city decoration but also a functional historical object.
