7 Hills of Rome

A small, unimportant hill, with few monuments. Caracalla's temple of Serapis was on it. To the northeast of the Viminal were the thermae Diocletiani, Baths of Diocletian, whose ruins were re-used by churches (now the Basilica of Santa Maria degli Angeli and the Museo Nazionale Romano) after the baths became unusable when the Goths cut the aqueducts in A.D. 537.
