The Pillsbury A-Mill on the east bank of the Mississippi River is a massive 1881 limestone mill building that was once the largest flour mill in the world. The building has been converted to residential lofts while retaining the industrial exterior and the historic designation that protects its facade. The building can be seen from the Stone Arch Bridge, its twin towers visible above the riverbank.
The complex is now primarily private residential, but the exterior is accessible from the riverfront path and offers a vivid sense of the industrial scale of 19th-century Minneapolis milling. The Mill Ruins Park immediately west, on the opposite bank, has interpretive signage explaining the milling history of both banks.
