The area around the Emonska ulica and Vegova ulica streets has existed as a street area since the 19th century, when the moat running along the eastern town wall of medieval Ljubljana was filled up. In the 20th century it was landscaped with terraces, benches, monuments, trees and a kiosk to designs by the architect Jože Plečnik.
Plečnik's earliest creation in the area was an obelisk dedicated to Napoleon and the Illyrian Provinces, erected in the Trg francoske republike square in 1929. The times when Slovenian inhabited lands were part of the French Empire's Illyrian Provinces was an important period in Slovenian history as the French authorities supported a Slovenian language-based education system and the development of Slovenian culture.
In 1932, a terrace with monuments to famous Slovenian musicians was built by Plečnik in front of the Glasbena matica building. During the construction of the National and University Library, another terrace was built on the remains of Ljubljana's Roman and medieval town walls and landscaped with a row of monuments to renowned Slovenian linguists and the poet Simon Gregorčič (1937). Alongside the University of Ljubljana building, the Vegova ulica street opens into the Kongresni trg square. As a final touch to the landscaping of the street, Plečnik built a weather house on the edge of the Kongresni trg square's Zvezda park.
