Incidently, this is a town hall, right?

In that case, just putting a name on the building will have no real effect.  The map will understand it only as "a building with a name".
If someone wants to lists all the town halls in Benin, they will never be able to find this one.  You should add an extra tag to the building, namely https://wiki.openstreetmap.org/wiki/Tag:amenity%3Dtownhall

Hope this helps.
