The spiritual and civic centers of roman cities were called this is where all the public buildings were located.

In my opinion, the correct answer is forums. They were public places that were first and foremost used as marketplaces. Since they were the most crowded public places, they were also used for all kinds of festivities, political meetings and discussions. They were also the religious centers of cities, with temples and public baths. Their role was much the same as the role of agoras in Greek cities.

The spiritual and civic centres of Roman cities were called Domes. It comes with a huge and definite design. Domes were also called temples, thermae, palace, and later on changed to church. Monumental domes also began to emerge in the 1st century BC.
