Piazza Navona

Piazza Navona is a Baroque square from the late 15th century that features several impressive statues and fountains from Baroque architecture. The square was built in the 1st century on a former Dominitian's stadium, and now the ruins are a part of the Unesco World Heritage. You can still recognize the square's unique shape and visit the ruins of the stadium 4.5 meters (15 ft.) under Piazza Navona. Later in history, the square turned into a lake during the summer to stage famous naval battles.
