piazza Mattei
One of my favorite in town. It is a jewel immersed in in a network of tiny alleys, in the proximity of Largo argentina and the Jewish Ghetto.
Built between 1581 and 1588 on a project by Giacomo della Porta (1533-1602) with the sculptures by Florentine Taddeo Landini. The four turtles placed on the edge of the upper basin, attributed by tradition to G.L. Bernini, constitute a beautiful completion of the work carried out during the restoration of 1658-59, under the pontificate of Alexander VII (1655-1667)
