'''Fontana della Barcaccia''' (English: "Fountain of the Old Boat") is a
Baroque fresh-water
fountain in
Rome,
Italy in the
Piazza di Spagna, just below the
Spanish Steps, and is so named because it is in the shape of a boat.
The fountain was commissioned by
Pope Urban VIII and was completed in
1627 by
Pietro Bernini and his son
Gian Lorenzo Bernini.
The shape was chosen because, prior to the river walls being built, the
Tiber often flooded and in
1598 there was a particularly bad flooding and the Piazza di Spagna was flooded up to a meter. Once the water withdrew, a boat was left behind in the square.
