Knez Mihailova Street (Serbian: Кнез Михаилова улица, romanized: Knez Mihailova ulica, officially: Улица кнеза Михаила, Ulica kneza Mihaila) is the main pedestrian and shopping zone in Belgrade, and is protected by law as one of the oldest and most valuable landmarks of the city.

Named after Mihailo Obrenović III, Prince of Serbia, it features a number of buildings and mansions built during the late 1870s.

One kilometer long Knez Mihailova Street was protected in 1964 as the spatial cultural-historical unit, the first cultural monument of that type in Belgrade.

Also in the Čika Ljubina, remains of the house from the 4th century was discovered in 2008, which included the part of the floor and doorstep of the main entry door.

Next to this locality, at the corner of Knez Mihailova and Kralja Petra, an area paved with the cobblestone dating from the 2nd century was discovered.

In 2008 in Čika Ljubina Street remains of the house from the 4th century was discovered, which included the part of the floor and doorstep of the main entry door.

The fourth reincarnation of the fountain, which stands today, was built in 1987 within the scopes of a major reconstruction of the street, which adapted it into the pedestrian zone.

[8] Today located in front of the "Zora" palace (which hosts the Servantes Institute), it was sculptured by Aleksandar Deroko from the white Venčac marble, and is described as the "monument to the old fountain".

When Archbishop of Canterbury visited Belgrade in May 1946, huge crowd of people spontaneously gathered in the Knez Mihailova, effectively forming a procession.

Previously nonexistent oak avenue through the middle of the street was also introduced, so as vintage looking candelabra which resemble the historical, gas ones.

[16] In 1988 area around the Palace Albania, Hotel Majestic and “Jadran” cinema were also reconstructed, and a new fountain and mini-amphitheatre were placed in the section of the street where it enters the Republic Square.

[2] Reportedly, as of mid-2010s, much of the street's real estate is owned by Serbian tycoons of the day such as Dragan Đurić, Miroslav Mišković, Miodrag Kostić, Philip Zepter, Radomir Živanić, Vojin Lazarević, Tahir Hasanović, and Radivoje Dražević and it houses their respective business holdings.

The area is bounded by the streets Knez Mihailova, Kralja Petra, Uzun Mirkova, Studentski Trg, Vase Čarapića, Republic Square, Sremska, Maršala Birjuzova, Carice Milice, Cara Lazara, Gračanička and Pariska, and covers 18 ha (44 acres).

Art historians and conservationists proposed the expansion of the Knez Mihailova's spatial unit (declared in 1964) to include Republic Square, green area along the Pariska Street and blocks surrounding Palace Albanija.

The street has been named one of the most beautiful pedestrian zones in South East Europe and is a constant buzz of people and tourists.

The street is home to Serbian Academy of Sciences and Arts (SANU), Instituto Cervantes, Goethe-Institut, Institut français de Serbie, as well as many other leading shops and several cafes.

[22] One can find international clothing brands such as Mango, Zara and Zara men, Gap, Nike men and women, Replay, Diesel, Terranova, Sephora, New Look, Swarovski, Cesare Paciotti, Tally Weijl, Miss Sixty, Bata, Bally, Aldo, Adidas, Vapiano, Monsoon Accessorize and many more shops.

The latest confirmation of this occurred in late November 2007 when the 485m2 parcel belonging to state owned company Jugoexport was sold for €15 million, which works out to some €32,000 per square meter (~ $35,741 as of August 2016 rates).

[23] Near the end of the street, between Knez Mihailova and Uzun Mirkova, a large complex of Rajićeva Shopping Mall was constructed.

Zoran Manević, former president of the Club of Architects, called it a "monstrosity" while member of the Academy of Architecture, Branko Bojović, said there are many cultural issues why it shouldn't be built, naming just one of them, the Roman remains in this entire section of Belgrade, which are shallow and conserved under the ground.

Israel investor, "ABD", daughter company of "Ashtrom", cited the reasons for that as the long and complicated process of obtaining permits, unregulated property ownership, archaeological explorations and financial problems due to the global economic crisis.

[29] Writer and former ambassador Dragan Velikić called it "architectural abomination in the heart of Belgrade - steel jaws of the shopping mall which swallowed the building of the City Library", referring to the edifice as the Rajićeva Cave.

[30] Architect Slobodan Maldini [sr] said that the project ruined both the archaeological locality and the architectural core of the city,[31] and that the protected zone of Knez Mihailova has been degraded by it.

This extension of the Knez Mihailova Street would create a continuous pedestrian zone from the Terazije, Republic Square and Palace Albania to the Kalemegdan Park, the Belgrade Fortress and the rivers.
