As part of the city festivity celebration, the days of the city’s patrons Holy Emperor Constantine and Empress Helen, the guest from the twin cities and friend cities of Serres (Greece), Kursk (Russia), Vienna (Austria) and Izmit (Turkey) visited the memorial room of the Serbian Army Land Forces. The delegations accompanied by Nis City Mayor Darko Bulatovic were welcomed by the Commander of the Land Forces Lieutenant Colonel Milosav Simovic, and he introduced them to the idea of establishing such a setting and the process of the creation of the Memorial Room. According to General Simovic, the purpose of the Memorial Room and Museum is to save from the oblivion all soldiers, officers and civilians who were killed during the wars, from 1804 to the present, and to pay tribute to all those who sacrificed their lives for the creation of modern Serbia and the preservation of its freedom. Apart from the setting that includes an overview of the activities of the units of the Land Forces since their creation, the whole process of the creation of the Serbian state and army from the Middle Ages to the present is shown. Uniforms, weapons, flags, coats of arms and features of all units throughout history, reviews of the war events and battles of the Serbian uprising until the last conflicts in the territory of Kosovo and Metohija are exhibited. All commanders and heads of military units throughout history have been recorded, as well as cooperation with other armies, local self-government, state bodies and citizens’ associations. The greatest attention of the guests was drawn, however, by the memorial room with more than 16,000 names and photos of dead soldiers and civilians who died in all wars since the beginning of the 19th century to the NATO aggression and the arrival of KFOR in the territory of Kosovo and Metohija, among which there are the names of the Greek soldiers who fought with the Serbian army in World War I, as well as the names of British, Russian, French soldiers and civilians killed in this area in the struggle for the liberation of Serbia from the occupiers.
