After the start of the Civil War in Russia, many architects left the country and continued their work abroad. They mainly focused on designing Orthodox churches, which can still be seen in Brussels, Prague, Paris, and New York. However, their work was not limited to temples. For example, architect Nikolai Krasnov built several government buildings in Belgrade, the most notable of which is the building of the National Assembly of Serbia.

Before the revolution, Nikolai Krasnov served as an architect for Nicholas II and created the Livadia Palace in Yalta for the emperor. After the tragic events surrounding the execution of the royal family, he could not remain in Russia and first went to Constantinople, then to Malta, and in 1922 settled in Belgrade. There, he began working in the Ministry of Construction and designed several important buildings for the city, including the parliament, the Ministry of Finance (now the government of Serbia), the Ministry of Forests and Mines (now the Ministry of Foreign Affairs), and the state archive.

Before Krasnov's arrival, three architects had worked on the parliament building project, but in 20 years they could not progress beyond the first floor. Krasnov completed the construction in two years, designed the interior, and laid out the park near the assembly. The main sculpture in this park was created by another Russian émigré, Roman Verkhovsky.

The building of the National Assembly is done in the Neo-Baroque style. A light green dome rises above it, with two smaller domes on the sides. The main entrance is designed as a portico with columns. The interior walls are decorated with stucco and frescoes, the floors and stairs are made of white marble, and bronze statues symbolizing education and justice are installed in the niches near the stairs.
