Following the Austro-Hungarian Compromise of 1867, the extensive economical, industrial and cultural development taking place proved that the formerly active coops did not function according to the requirements of the times.

It also organized trade authorities, ordering the formation of trade associations on the territory of every trade authority to which every tradesman was obliged to join.

The first time the chance to form a school chapel during the history of the 100-year-old town occurred in the 1920s. On Sundays, the desks were taken out of the sole schoolroom in the village, by then a municipality. Then, the schoolroom was refurnished with equipment from the chapel. One of the exhibition rooms shows original items from the chapel. The visitors can see the original tabernacle, the stoop, as well as a number of statues and flags.
