David's Been Here is touring all the top sites, main attractions and best day trips all throughout Bulgaria. In this short clip, David brings us 45 minutes outside the city of Plovdiv to the ancient ruins of Hisarya. Once known as Diocletianopolis, this ancient Roman town was built atop a preexisting Thracian settlement, which is home to some of the country's best-preserved Roman walls and gates. Tour around the historic ruins of this Town of Emperors, experience its famous mineral-rich waters or just kick back for a quiet relaxing weekend in Hisarya. Also home to a nearby Roman tomb, this historically significant destination is a great day/weekend trip in central Bulgaria.
