Continuing straight to the end of Pod Kaštany Square on the right-hand side, you‘ll find the formal entrance to yet another Petschek villa – today the Embassy of the Russian Federation. The villa, designed in French Baroque style, is once again by Max Spielmann, the Petschek family architect. The huge complex spreads out over one hectare and includes a garden with pond. The historic building is used for formal embassy functions.
