The city of rome at its peak.Controlling sections of the cities divided by certain factors.Regions could include the Entertainment(circus maximus, ampitheatres, public baths), Political district(hold the forum, the senate building and such), Residential(Certain key roman houses), and Religous district(the temples of the various gods).to add some vriety maybe have senate members/consuls scattered throughout the city as a autodeploy.
Also could have legions around city and certain bonuses for them.
Just a thought I had
