Máté Nöpauer (around 1719-1792) was the most kept employed master-builder between the 1750s and 1780s in Buda, his leadership in the architecture of baroque churches in Buda is undeniable. Nöpauer was the heir of Kristóf Hamon (1693-1748) master mason in Buda both in professional activity and in family connection: finished the buildings uncompleted because of death of Hamon, married Hamon's widow, brought up and taught in profession Hamon's children. Nöpauer finished building the St. Anna's church (1748-62) and the parish church in Óbuda-Újlak (1748-68) both were started to be built by Hamon. He formed the main front and the sanctuary of the St. Katalin's parish church in Tabán (1749-65). His self-built churches are the Franciscan church on Margit boulevard (1752-67) and St. Flórián's church in Víziváros (1759-60). In all of his works Nöpauer strove for the simplicity and obvious structure. His churches imitate the simplified tidying, developed from the space-system of the church of Il Gesú in Rome, except for the central space with elliptical ground-plan of St. Anna's church, which is unique in Hungarian architecture. He generally manipulated the walls flat, also kept away from the more complicated space-effects by the superstructures.
