The Roman colony of Deultum is the oldest Roman city in Bulgaria founded in AD 70. Its archaeological research began in the 1980s. From December 2023, a team of specialists from NAIM-BAS, Sofia University St. Kliment Ohridski and Municipal History Museum-Sredets is implementing a three-year projectfunded by Bulgarian National Science Fund (КП-06-H80/7 from 8.12.2023). Its main goal is to explore a possible fundamental change in the historical narrative of Deultum by combining the previous scientific approaches with those of digital humanities and archaeological sciences.
