Roman period Predecessor of Belgrade was Singidunum, Celtic and, later, Roman fortified town. The original earthen and wooden fort stretched around the Studentski Trg and Knez Mihailova Street. The oldest Roman graves were discovered in this section, dated to the 1st and early 2nd century. The central axis of the city grid was in the modern Uzun Mirkova-Studentski Trg-Vasina-Republic Square direction, thus the area od modern square was the "heart" of ancient Singidunum. Part of the main axis was an additional turning at modern Rajićeva Street. There was a gate at the entrance into the military camp. The gate was located where the City Library, the last building in the Knez Mihailova Street before the Kalemegdan Park, is located today. The building had the system of floor and wall heating, made of special, hollow bricks which allowed for the hot air to circulate through the rooms (
tegula mammata and
tubula). The canals which conducted the water to the thermae, and were discovered in 2013 when the
manhole was dug in front of the
Ethnographic Museum. The canals were connected to the main aqueduct built by the Romans, which conducted water from the springs in modern
Mali Mokri Lug. The thermae was built by the Roman military, as attested by the inscriptions on the bricks which contain markings of the
Legio IV Flavia Felix. The entire area of the park is actually within the borders of the "Protected zone of Roman
Singidunum". It is situated in the area that used to be the civilian sector of the city, outside the fortress. The remnants were visible until 1978 and due to the lack of funds to continue excavations or to cover it with the roof or a marquee, the remains were conserved and buried again. Also, in 1821, the state government decided to put the food trade in order and to establish the quantity and quality of the goods imported to the city. Part of the project was introduction of the
excise on the goods (in Serbian called
trošarina) and setting of a series of excise check points on the roads leading to the city. That same year, the city's first proper greenmarket became operational. Originally, it opened in 1824 right across the
Belgrade Fortress, in the modern
Pariska street, stretching between the
Uzun Mirkova and
Knez Mihailova streets, where the City Library is today. Only 4 days later, it was moved to the location above the old, defunct Turkish cemetery. The chosen location was situated above the
Tekija building and the Kizlar Aga's Mosque, close to the starting section of the
Tsarigrad Road. The market was soon equipped with market stalls for selling fruits and vegetables and barracks for the dairy products, eggs and dried meat. Raw meat was not allowed at the market. Poultry was sold alive and only in pairs. Other meat was prepared and sold in butcher shops and, since there were no refrigerators, had to be sold by noon. Apart from being the first arranged and planned market in the city, it also was the first to have a sanitary inspection which checked the hygiene, quality and freshness of the goods. As per Serbian-Turkish agreement anyone could bring and sell goods, the market quickly grew and became city's commercial center. Though it was officially named "Saint Andrew's Market" it became known as the Great Market (Serbian:
Velika pijaca or
Veliki pijac). In the
kafana Kod Rajića junaka serbskog, prince
Mihailo Obrenović organized festivities after he was handed over the
keys to the city from the Ottomans, who had to evacuate the
Belgrade Fortress. Prince Mihailo was assassinated on 10 June 1868. The Board for the erection of the monument was formed already on 14 June 1868 and decided to collect donations for the construction of both the church in
Košutnjak, at the assassination location, and a monumental sculpture in the city itself. Russian sculptor
Mikhail Mikeshin, after arriving in Belgrade in October 1868, and inspecting the city, in cooperation with the government and the Board, proposed two designs for the monument to the prince, which was to be erected at the Great Market. After the public display, the citizens apparently liked the designs and approved the building. However, the process of building the memorial dragged on, and in 1871 Mikeshin's propositions were rejected. Also in 1871, the government opted to build only the monument in the city. It announced the international design competition but dissatisfied with the results, the government repeated the competition in 1873. This time, the location for the monument was set at the Theatre Square (modern Republic Square), across the
National Theatre in Belgrade, which was built by prince Michael. Its were the
Prince Mihailo Monument was ultimately built in 1882. In one of the houses at the future square, the
Red Cross of Serbia was founded on 6 February 1876. During the
Serbian-Ottoman wars from 1876 to 1878,
Mikhail Chernyayev headed a corps of Russian volunteers to Belgrade. A mobile military church dedicated to the Holly Prince Alexander Nevsky also came from Russia and followed them to the battlefields. It was located at the Great Market in 1876, and was used for
eucharists and
requiem masses. When the church was permanently moved in 1876, residents of Dorćol formed a board for the construction of the church and a small, stone church was built further down the hill and a bit below the modern one, dedicated to Alexander Nevsky, too. In turn, it was demolished in 1891 and modern Church if the Holy Alexander Nevsky was finished by 1930. First modern Belgrade's urbanist
Emilijan Josimović suggested dislocation of the market in 1887, as it was placed in the sole center of the city. Plus, he deemed it inappropriate for the Great School to be across the market. But when the
horse-drawn tram was introduced in Belgrade 1892, and it passed through this part of the city, the market actually bloomed even more. Josimović met with much resistance and only some time before his death, he managed for the city to decide to split the market in two and to form a park in one of the sections. The open space area around the market, which was now a defunct Turkish cemetery, and the northwestern section were turned into the park, as Josimović originally envisioned. He also proposed for the nearby buffer zone between the city and the Fortress to be adapted into the
Kalemegdan Park, as he considered parks the "air reservoirs". The park was opened on 11 May 1897, just two weeks before Josimović's death. On the same day, the monument to
Josif Pančić, work of sculptor
Đorđe Jovanović was erected in the park. As the monument was covered with cloth for a long time, citizens colloquially nicknamed the square a "plateau of the bagged man". The market itself continued to operate until 1926 when was finally closed. With the closing of the Great Market, city government built several other markets in the city, bit further from the downtown:
Zeleni Venac,
Kalenić market, Bajloni market and Jovanova market. The park that was created was named Pančićev Park, after his monument in the park, and is today known as the Akademski Park. Pančić's monument was coupled with the monument dedicated to
Dositej Obradović in 1914, which was transferred to the Akadameski park in the early 1930s from his previous location at the end of the
Knez Mihailova street. The square was finally formed in its present shape by 1927, with the park in the central part. Park was planned by architect Đorđe Kovaljski while the recognizable enclosure and the gates were added in 1929, on the project of Milutin Borisavljević. == Characteristics ==
