After the Bombardment of Brussels by French troops under maréchal de Villeroy, Maximilien-Emmanuel entrusted Bombarda with the construction of a new theatre right in the heart of the city – the Théâtre "sur la Monnoye", which opened in 1700. The Académie royale de musique in Paris was then in financial difficulties and its director Jean-Nicolas de Francine was unable to remedy the situation alone. The able financier Bombarda was thus called to the Académie in 1703 and left the elector's services to set up himself and his family in Paris in 1705, in a house on rue d'Argenteuil, not far from the Palais-Royal, where he died in 1712.
