In connection with the move of Birgitta Hospital to the new hospital district in 1951, there were plans for new utilizations of the old monastery building. At that time two important discoveries were made: the main building of the nunnery with the dormitory was preserved and the building originally consisted of the former royal palace of the Folkunger dynasty from the 13th century. It was assumed earlier that the palace had been demolished when the monastery was built.
In 2016, the 60th anniversary of the discovery was celebrated on August 26 and November 19.
