Imperial Baths (Kaiserthermen)

Year 307 (CCCVII) was a common year starting on Wednesday (link will display the full calendar) of the Julian calendar. At the time, it was known as the Year of the Consulship of Valerius and Constantius (or, less frequently, year 1060 Ab urbe condita). The denomination 307 for this year has been used since the early medieval period, when the Anno Domini calendar era became the prevalent method in Europe for naming years.
