It appears there might be some confusion in your request. Asenovgrad is a town in the Plovdiv Province, Bulgaria, but "GCAO" does not correspond to any known designation related to this location. Could you please provide more information or clarify what you mean by "GCAO"? This could possibly refer to a specific organization or an event taking place in Asenovgrad, but without additional specifics, it's difficult to provide a detailed description.
Asenovgrad, which is known as the "City of Brides", is the largest town in Bulgaria not to be a provincial center. The town is surrounded by many archaeological, historical and natural landmarks, since it was a focus for Thracian culture. Furthermore, it is very attractive for tourists due to its location close to the famous ski-resort Pamporovo.
