The building was meant to resemble on a smaller scale the famous Royal Belvedere (palace) of Vienna, which likely was one of the reasons along with other religious conflicts that made Empress Maria Theresa of Austria repudiate the founder, Adam Patachich, a Croatian nobleman and the bishop of Oradea between 1759 and 1776; he was then sent to another diocese, in Kalocsa, Hungary.
After completing his studies in 1878, he would return to teaching and also serve as an assistant at the Haynald Observatory in Kalocsa.
We possess, however, a complete version made by an unknown hand in the thirteenth century and preserved in two manuscripts, one at Heidelberg and one belonging to the archiepiscopal library of Kalocsa.
Stephan Franz Lajos (or Ludwig) Haynald (b. at Szécsény, 3 October 1816; d. at Kalocsa, 3 July 1891) was a Hungarian Archbishop of Kalocsa-Bács, naturalist, and Cardinal.
Zoltán Bagó (born on 10 January 1975 in Kalocsa) is a Hungarian politician and Member of the European Parliament with the Hungarian Civic Party, part of the European People's Party.
