The oldest parts of the historic city center are nestled right next to Kalemegdan. Take a walk along Kosančić's Wreath (street) to the residence of Princess Ljubica, the National Bank of Serbia, Knez Mihajlova Street. This pedestrian district and main city street, today protected by law, is one of the oldest and most valuable places in Belgrade, with a whole series of impressive buildings and houses that sprung up in the late eighties of the 19th century. Today it is the most important business district of Belgrade and the seat of many state institutions. Trg Republike - the main city square - is a favorite place where you can find the National Theater, the National Museum, the monument to Prince Mihajlo Obrenović and the monument to the famous Serbian writer Branislav Nušić.
