Just off Kneza Mihaila,Republic Square really makes you feel like you’re in the very center of Belgrade. Surrounded in a mix of elegant historic buildings as well as socialist-era ones, you get the classic mix of Belgrade’s architecture. Two of the nicer buildings here are the National Theatre and National Museum of Serbia, both overlooking the mounted Monument to Prince Mihailo. With people constantly passing through and filling the outdoor areas of nearby cafes and restaurants, this is a great place to feel the energy of the city.
