Stora salen was renovated for the 100th anniversary of Akademiska Föreningen in 1930. The restaurant’s former outdoor terrace was also incorporated into the building in 1946, signed by Hans Westman.
When the old house from 1851 was rather outdated and impractical, it was found for good in 1951 to demolish the entire Stora salen and all the small buildings around the courtyard. Hans Westman then recreated the interior of the house from the ground. Källarsalen was added and the ground floor’s club room was converted into a gigantic café room called Athen. Stora salen changed character into a bright and airy room instead of the old knight’s hall. Through Konsertsalen, the house was given a new stage. The upper floors were used as student rooms and student association offices.
In the 1970s, much of the student life was moved out to the nations’ own houses and to the newly built Sparta. But after a few years, an opinion was aroused to bet on the old castle in the middle of Lund. In 1980 Stora salen was renovated again. Café Athen had then become a bookstore under the direction of Akademiska Föreningen called Akademibokhandeln. In the old café Tua was a Pressbyrån kiosk. Although much of the business came back to the house in the 1980s, it was clear that a major new renovation was needed to save the castle from decay. At the beginning of the 1990s, a renovation was made financed by loans with generous terms from the local business community, loans that over time have been donated. During this renovation, Lilla salen was restored to its original colour scheme.
