I still say its a mishmash of several european influences not just one
Where's Jesus? Isn't he knowledgable in Architecture? Elaborate for us, Jesus.
You may be right Capoix.
Looking at the drawing we see Greco-Roman columns......and the Milot church shows an eastern European influence.
Prussian King Frederick II's sans souci park had several structures. His sans Souci summer retreat was done in a German Rococo style while the larger "New palace" shows more of the Baroque style popular at the time......but he was so involved in the design of the samller Sans Souci palace, that they often refers to that style as Frederican Rococo.
Kristoff palace definitely shows no rococo influence. It does appear to have incorporated several styles.
Kristoff simply choose to name his palace after the one in Potsdam.
As for the Citadelle, it is a departure from European forts at the time which were mostly designed for the coast. We would have to go back to medieval Europe to find inland mountainous fortifications.....they are however not similar to our Citadelle.
I think both the Citadelle and Sans Souci are local adaptations. The sub-floor cooling of the palace and the collection of water for the citadelle are examples of local engineering adaptations.
Finally; the fact that "the man" has not claimed these to be imitations and "the man" is still marveling at the construction of the Citadelle may be proof that these monuments are ours...yes with European help and inspiration...but Haitian after all.
