Baths of Constantine-Where

These were the last of the great baths of Rome, and were built by Constantine on the Quirinal Hill. They were probably built before AD 315. They suffered greatly from fire and earthquake, but were restored in 443 AD. Very little from the baths survive today except some important statues that used to adorn the complex. These statues include Constantine and his son Constans, the Nile and Tiber river gods,  and the bronze boxer.
