Among the architects invited to work in Bulgaria were Friedrich Grünanger, Adolf Václav Kolář, and Viktor Rumpelmayer, who designed the most important public buildings needed by the newly re-established Bulgarian government, as well as numerous houses for the country's elite. Later, many foreign-educated Bulgarian architects also contributed. The architecture of Sofia's centre is thus a combination of Neo-Baroque, Neo-Rococo, Neo-Renaissance and Neoclassicism, with the Vienna Secession also later playing an important part, but it is most typically Central European.
