16 SEPTEMBER 1937 – TO THE END OF THE CENTURY
The first airfield in the city of Sofia was located on the territory of the present Central Railway Station. The first domestic flights began with the transportation of mail shipments along two routes: Sofia – Gorna Oryahovitsa – Varna – Ruse and Sofia – Plovdiv – Yambol – Burgas.
Since the early 30s of 20th century, all flights were operated from the unpaved runway in the village of Vrazhdebna, later chosen for the construction of a civil airport by a Decree of Tzar Boris III, dated 16 September 1937. This is considered to be the birth date of Sofia Airport.
Airport construction was carried out under the governance of the Directorate of Civil Aviation to the Ministry of Railways, Posts and Telegraphs.
