Another sculpture, Hercules and Cacus by Baccio Bandinelli is at the right entrance of the Palazzo Vecchio. It is a symbol of physical strength of Hercules over Cacus, a fire-breathing monster that he killed.
The Equestrian Statue of the Grand Duke Cosimo I at the square.
Loggia dei Lanzi is an arched gallery built in the 14th century exhibiting a number of impressive sculptures that can be visited for free. The collection has actually expanded over time with some even installed centuries apart. A pair of lion statues can be found at the entrance of Loggia dei Lanzi.
An interesting angle discovered by SL, the lion is eating David!
Some of the notable sculptures in the gallery include: Perseus with the Head of Medusa.
Menelaus supporting the body of Patroclus.
And Hercules Slaying the Centaur Nessus.
Also in front of the palazzo is the Fountain of Neptune, a work by Bartolomeo Ammannati with some assistants. Again, the Neptune is a copy while the original sits in the National Museum.
As a work of art it should be appreciated but unfortunately it has suffered numerous damages resulting from vandalism. After being restored so many times, security cameras are installed nearby to ensure no future damage would occur to it anymore.
While impressive, I guess only humans would be capable of admiring the fountain. To the birds, it is just another place for them to drop their things.
