Piazza Martin Lutero, Colle Oppio Park

Colle Oppio (The Oppian Hill) is the southern spur of the Esquiline Hill, one of the Seven Hills of Rome, Italy. It is separated from the Cispius on the north by the valley of the Suburra, and from the Caelian Hill on the south by the valley of the Colosseum. The Oppius and the Cispius together form the Esquiline plateau just inside the line of the Servian Wall. The Oppian Hill Park is considered to be an archaeological park. Much of the Domus Aurea (Golden House of Nero) lies under it, and it also contains the ruins of the Baths of Trajan and the earlier Baths of Titus.

Park next to or around the Domus Aurea. It is a lovely place to stroll, there are fountains and a large playground for children.
