Sofia
The Bulgarian capital Sofia is a veritable treasure trove of historical, cultural and culinary treasures. Above all, the density of places of worship of the most diverse religions in such a small area is unparalleled anywhere else in the world. The so-called "Square of Tolerance", ancient Catholic and Orthodox churches, the magnificent Nevsky Cathedral and historically valuable monuments from the time of the Bulgarian Revival are among the most important sights of Sofia, along with art museums and the Palace of Culture.
