Don’t know the sign you’re looking at. The major part of the building is City Hall. Which I think is an excessive structure, don’t get me wrong.

The building I refer to has a very big sign near the top of the face above all the artsy glass that says PERFORMANCE ART CENTER. If there is a sign that says Municipal center or Police station or anything else, that sign is very small and well hid.
From memory, I believe there are little signs telling people where to walk and things like that.
