Old Louisville is a historic district and neighborhood in central Louisville, Kentucky, United States. It is the third largest such district in the United States, and the largest preservation district featuring almost entirely Victorian architecture. It is also unique in that a majority of its structures are made of brick, and the neighborhood contains the highest concentration of residential homes with stained glass windows in the U.S. Many of the buildings are in the Victorian-era styles of Romanesque, Queen Anne, Italianate, among others; and many blocks have had few or no buildings razed. There are also several 20th-century buildings from 15 to 20 stories.
