The Church of the Assumption of the Blessed Virgin Mary in Cieszyn, located on Londzina Square, is a building dating from the years 1697-1718. It was later rebuilt. The predominantly Baroque look of the church was changed by the erection of neo-Classical façade in the late nineteenth century. The history of the church is associated with the nearby monastery of the Brothers Hospitallers of Saint John of God. These monks are known primarily for looking after the sick, running pharmacies and herbal medicine.
