If your Belgrade friends tell you to meet them in the city center, more precisely at 'the Horse', then they literally mean that you should meet at the horse. But don't be confused, there is no stall in the city center. They are just telling you in slang that your meeting place is the main city square with recognizable statue of Prince Mihailo riding a horse.
Square is officially called Republic Square and it represents the true and very hearth of the city. This is the main meeting place of all kinds, here you can enjoy lazy afternoon while sipping coffee in the mild autumn Sun, attend concerts, various performances or just hang around doing nothing special.

Republic Square has important, though not very attractive place in Belgrade history. In this place used to stand Stambol Gate, the furthest outer gate of 19th century Belgrade, and here Turks executed convicts by hanging. As soon as they left the city, Prince Mihailo ordered demolition of the gate. National Theater was the first building constructed on this place in 1869 and 19 years later, statue of Prince Mihailo was erected. As years passed, square became center of the modern Belgrade with everything built around it. During its history, Square changed its look for several times. Until end of WWI, trams ran through the square, but after that time Republic Square slowly got nowadays look.

MONUMENT OF MIHAILO OBRENOVIĆ is the work of Italian sculptor Enrico Pazzi and it was erected in 1882. It represents Prince riding a horse and pointing towards South. Cities that were given away by Turks and scenes from Serbian history are represented on pedestal of the monument. Pazzi himself was so amazed by Serbian mentality, that after leaving Serbia he wrote that although he belongs and feels like Italian, his heart belongs to Serbia.

While standing in front of the monument and looking around, you can notice a couple of notable and important buildings and places. From your left you can see building of National Theater, built in 1869. At the time of opening, it could seat up to 714 people. However, during time it was reconstructed, two stages were made and present look was given in 1898.
Left from the National Theater stands park and plateau that was names after Zoran Djindjić. He was the first prime minister of newly formed government in 2000, after the fall of the regime of Slobodan Milošević. Djindjić was shot in 2003 and in memory to his work plateau was named after him.
Right from you stands Boško Buha Theater, the first theater that was dedicated to children and youth in Serbia. Last, but not the least, behind you stands the most important cultural facility in our country, National Museum. It can boost with collection of more than 200,000 paintings, drawings, graphics and sculptures. Unfortunately, due to never ending reconstruction most of this works could not be exhibited. They are kept in the cellar of the museum, but from time to time, National Museum organizes exhibitions in its atrium.
