The architecture of Leeds, a city and metropolitan borough in West Yorkshire, England, encompasses a wide range of architectural styles and notable buildings. As with most northern industrial centres, much of Leeds' prominent architecture is of the Victorian era. However, the City of Leeds also contains buildings from as early as the Middle Ages such as Kirkstall Abbey, one of Britain's best preserved ruined Cistercian monasteries, as well as examples of 20th century industrial architecture, particularly in the districts of Hunslet and Holbeck.
