Austins was a department store in the Diamond area of Derry in Northern Ireland. The store was established in 1830 and until 2016 remained standing as the world's oldest independent department store. The building measures 25,000 square feet (2,300 m2) and is five stories high, with an Edwardian-style baroque exterior built in 1906 by MA Robinson after the original building was destroyed by fire. The Austins Department store building in the Diamond was owned by the City Hotel Group, but the actual retail operation was leased to Hassonzender, which went into liquidation.
