Does constructing beautification buildings have any in-game effect?

Question

In Anno 1404, there are quite of few beautification buildings that the computer players use to great effect. While they are nice, I have better things to spend my resources on if these buildings have no pay-off.

Other than looking nice, does building beautification structures, streets, and parks have any effect?

Answer 1

Those buildings have absolutely no effect, only build them if you care about how your city looks.
