English: The Parish Church of the Assumption (Maltese: Knisja Arċipretali ta' Santa Marija), commonly known as the Rotunda of Mosta (Maltese: Ir-Rotunda tal-Mosta) or the Mosta Dome, is a Roman Catholic parish church in Mosta, Malta, dedicated to the Assumption of Mary. It was built between 1833 and the 1860s to neoclassical designs of Giorgio Grognet de Vassé, on the site of an earlier Renaissance church which had been built in around 1614 to designs of Tommaso Dingli.
