From the website of the Budapest History Museum:
The Municipal Gallery operates as part of the Budapest History Museum, in the building of the Kiscelli Museum. While its 40-thousand-piece fine arts collection is of national importance, the works can only be seen occasionally due to the lack of a permanent exhibition. The temporary showcase Municipal Gallery – Works and Stories aims to make up for this shortfall by putting a nearly 150 pieces strong collection on display, presenting works from the birth of Hungarian modernism to the present day and providing a comprehensive account of the history of Hungarian art from the end of the 19th century to contemporary artists.
