The old Abbey mill used to belong to the Abbey church and was of great importance to the monks in the economic independence of the abbey.
On August 5, 1992, the old abbey mill was destroyed by a disastrous explosion in the bed of the Cicindria creek.
In 2018, the non-profit organization Abdij, Stad & Regio (ASR), in cooperation with the city of Sint-Truiden and Molenzorg Zuid-Limburg, started redeveloping the old mill site to make it accessible again.
ASR has set up, in the adjacent old farm buildings, a fascinating exhibition on the history of these and other water mills in and around Sint-Truiden.
