Which is correct? Are "municipality" vs and "city hall" are the same?

The city hall builds a library.
The municipality builds a library.

Please note my corrections above, and note that I have changed your thread title. Titles should include, ideally, the entire sentence you are asking us to look at. Your actual question (in your case, "Are "municipality" and "city hall" the same?") should appear only in the main body of your post.

A city hall can't build anything. It's an inanimate object. I'm not sure what you think "the municipality" means here.

Who is in charge of the construction? People often try to take credit for other people's work.
