Very clever buildings. In effect they allow not only optimization, but also city-specific mitigation of whatever's worrying you about a particular province.(EDIT: many of these IMO should have have capital-city civilization level prerequisites, as well as small civilization level impacts on the city of construction)That said, what bothers me slightly is: shouldn't it be the governor building them? There may be a conceptual inconsistency here. For the ruler to build certain of them outside the capital province, perhaps a small tyranny penalty is merited? (Possible exceptions: forts; and theatres built by Hellenistic monarchs, for whom cultural proselytization historically was their accepted "duty" and often obsession - although occasionally backfiring spectacularly, eg the Seleucids in Judea).Buildings also theoretically "should" add to the popularity and prominence of whoever's building them (which frequently was at least half the point, which is why they often were financed partly or wholly from the private funds of the builder), whether in the capital or in the provinces - perhaps some events might trigger upon completion? Not always "nice" events: governor popularity being a rather dangerous phenomenon... Or more comedic events such as the statue of the rulerConstruction-related event bonuses, if worked out comprehensively, might be used to (in aggregate) replace some or all of the simplistic "buying points" options (on the economy screen), which are mostly just abstractions for such infrastructure efforts.
