Here is a palace with the following caption, I can't really find anything on it, but would love to learn more if anyone has any information
Bolongaro Palace is a palace in baroque style built between 1772 and 1774 for Josef Maria Markus and Jakob Philipp Bolongaro. The two brothers were born in Stresa (Italy) and settled in 1735 in Frankfurt on the Main. There they owned the biggest tobacco manufactory of Europe and became very rich merchants. Because they were Roman-Catholic they did not get civil rights in Frankfurt and so they built their palace in Hoechst, a small city lying at the Main. Today it's a urban quarter of Frankfurt.
Bolongaro Palace is the biggest palace in baroque style that was not built for Royalty. It's situated on the Main and it's opened to the public.
The rooms are richly decorated with mirrors, wall paintings and wallpapers made of silk as well as arich decorated chapel. Today it's used for
concerts and theatre performances.
