Csorna has a central role in the region. It lost city status in 1871 but regained it in 1971.
Around 1180 the members of the Premonstratensian order organised a group to settle in Csorna. For a while, the order did not operate, but from the 17th century the two main landowners were the princely Esterházy family and the provostry of Csorna, thus the town became one of the Hungarian centres for the Premonstratensians in 1802.
The refurbished building of the monastery of the erstwhile Premonstratensian provostry dominates the town centre, as does the church refurbished on numerous occasions since its construction in the Middle Ages.
