I want to know the answer to the following question:
In what town is the oldest neoclassical architecture in Hungary?
All the background I'm provided with is that "In this town the triumphal arch and the neoclassical façade of the baroque Cathedral were designed by the French architect Isidor Marcellus Amandus Ganneval (Isidore Canevale) in the 1760s.". Is that enough to answer the question?
