Shrewsbury Flaxmill Maltings (previously the Ditherington Flax Mill), a flax mill located in Ditherington, a suburb of Shrewsbury, England, is the first iron-framed building in the world, and described as "the grandfather of skyscrapers". It is five-storeys tall. Its importance was officially recognised in the 1950s, resulting in it becoming a Grade I listed building. It is also locally known as the "Maltings" from its later use. The mill is owned by Historic England and is currently in use as a mixed-use workspace following its official opening in 2022. The complex has an exhibition managed by English Heritage.
