In my database I have: Zoo, Villa Comunale, Ravenna, Italy. Closed in 2003. I searched the parks of Ravenna. Do you know anything about the location (Parco Pubblici, Giardini Pubblici)? I also have: Atrox, Piazza XX Settembre 6, Bologna, Italy. Closed. Do you know if there was a reptile open to the public at that location in the past ?: It is currently the bus station.
The only current zoo opened in Ravenna is the Ravenna Safari Park, born on the ashes of an old Reptilarium from what I know, go check that out if you're interested
