Daniel, what I have tried to explain here is that there is a confusion between "Roman Style" The refined Classical style of Ancient Rome, and "Romanesque Style" the much less refined style that spread across Europe in the 10th- 12th centuries, an is strongly associated with large, organised Monastries like that at Cluny in France. 
This building is not Romanesque. It is Classical. Now I have looked a more pictures I see that it is clearly an "Ancient Roman" style building. That is why it uses the word "Roman" rather than just saying "Classical". (A Classical Revival building might look like an Ancient Greek building and not like a Roman one.) 

What I'm telling you is that your church is based on the buildings in the top line of the gallery. It is in the same style as the Classical Revival buildings in the middle line of the gallery. It has almost nothing to do with the Romanesque buildings in the bottom line of the gallery.
