The stadium is named after the Yunak sports societies which formed in Bulgaria in the late 19th century, themselves named after the word "yunak", meaning a strong young man.
In the 1920s–30s, immediately to the northeast of Yunak stadium, was built the smaller Levski Field, the home ground of SK Levski. In the 1950s, the BCP decided to build a new, larger national stadium on the site of Levski Field. As the new stadium would infringe on the north-eastern stands of the Yunak stadium, this was also demolished in order to make way for the Vasil Levski National Stadium, opened 1953. Because of this, Dinamo Sofia were given a new home in the north-eastern suburbs of the capital, while in the place of Yunak was built the much smaller Druzhba ("Friendship") stadium, which was used for many years as an ice rink.[3][4][5]
After the fall of communism, the disused ice rink regained the name of the original Yunak stadium, but was never again used as a sports facility and, as of the early 2000s, lies in ruins, which are visible between the national stadium and the Sofia Metro station that formerly bore the same name.[6][7]
The stadium has also been used for unorthodox "sports", such as live human chess during the reign of Tsar Boris.[8]
