Designed by Giacomo della Porta in 1581 and sculpted by Taddeo Landini, this 16th-century fountain, set in venerable Piazza Mattei, is Rome's most charming. The focus of the fountain is four bronze boys, each grasping a dolphin spouting water into a marble shell. Bronze turtles held in the boys' hands drink from the upper basin. The turtles are thought to have been added in the 17th century by Bernini.
