Rome is brimming with graceful piazzas and historic enclaves. Across which, some 2,000 fountains feature and some stand out as sculptural masterpieces. The most famous is the baroque Trevi Fountain, whose coin-toss legend may secure a return trip to the "Eternal City." In Piazza Navona, Bernini’s Fountain of Four Rivers stands, while in front of the Pantheon, the Fontana del Pantheon features an obelisk from the period of Ramses II (the 13th century BC) reaching skyward from a base adorned by four dolphins.
