On 19 July 1879 the Prince appointed the first diplomatic representatives abroad — Dragan Tsankov in Istanbul, the Ottoman Empire, Evlogi Georgiev in Bucharest, the Kingdom of Romania, and Dimitar Kirovich in Belgrade, the Principality of Serbia.

[5] That structure remained in force with little changes until the organisation was renamed as the Ministry of Foreign Affairs following the Dimitrov Constitution of 1947 and the establishment of the People's Republic of Bulgaria.

[6] Since 1983 the Ministry of Foreign Affairs has been based in a purpose-built edifice in the district of Slatina east of the Sofia city center, situated at 2 Alexander Zhendov Str.

It lies just northeast of the city's largest boulevard Tsarigradsko shose and its oldest park Borisova gradina.

[7][8] In the formal spaces in the interior, the dark marble and brass details bear similarities with the decoration style of the representative Sofia Largo of the 1950s.

Formally, the architectural image repeats characteristic patterns of the post-war modernism of the 1960s but the finishing works and stone cladding bear the high level of demonstrative luxury accepted as the norm in the buildings of the power of the People's Republic of Bulgaria at the time, such as the Boyana Рesidence.

[7] Elements of its architecture inspired other public buildings throughout the nation, including in the cities of Vidin, Ruse, Burgas, Pazardzhik and Troyan.
