Herculia, based on the site of Tác, Hungary.
The original town of Gorsium was rebuilt by Emperor Diocletianus in the 290's, after a series of barbarian raids destroyed the city. That's when the city got it's new name, Herculia.
In the fourth century many new buildings has been built on the main street: a governor's palace, a military barracks and multiple basilicas for the growing christian population.
Towards the end of the century, the city life was confined inside the protective walls, as barbarian incursion devastated the countryside.
