The meaning of ‘civil buildings’

The passage below is from The Library: A Fragile History by Andrew Pettegree.

On the night of Sunday 8 October 1871, a fire began in Chicago that would change the face of the city. At this point Chicago was fast emerging as one of the wonders of the new industrial world, a nodal point of the transcontinental transport network and the food distribution center of a hungry continent.

A tough city, and magnet for immigrants from all over Europe, the wealth of the Chicago elite was nevertheless expended to supply the customary accoutrements of metropolitan sophistication: churches and civil buildings, the Chicago Academy of Sciences, the Chicago Historical Society (home to a collection of more than 165,000 books) and the Illinois Library Association. The fire, which raged unchecked through all of Monday, swept all of this away, along with 17,450 homes,

rendering 95,000 people homeless.

In this passage does the underlined ‘civil buildings’ mean the Chicago Academy of Sciences, the Chicago Historical Society and the Illinois Library Association that follow civil buildings? Or does it have other meaning, such as public institutions?

Thanks in advance.
