Construction of the Fountain. Already in the fifteenth century a small Trevi Fountain was built here during the papacy of Nicholas V. In 1732, pope Clement XII commissioned Nicola Salvi to create a large fountain at the Trevi Square to replace the existing fountain.
The Chafariz dos Contos (Fountain of the Contos) was given by the country of Brazil as a gift to the city, as a symbol of friendship, and was assembled in Forest Park in 1956. It is a replica of the original fountain located in Ouro Preto, Brazil, built in 1745.
