Fontana delle Tartarughe

 
The name of this square (piazza Mattei) derives from the property that the Mattei family had in this zone. In the middle of it is Fontana delle Tartarughe, built according to a design of G.Della Porta in 1581-1584, with the bronze sculptures by T.Landini, and restored in 1658 probably by G.L.Bernini. Originally the place of four tortoises was occupied by four dolphins. The sculptures of tortoises were stolen several times, and finally replaced by copies (three originals are now in Musei Capitolini).
