The Downtown Waterbury Historic District is the core of the city of Waterbury, Connecticut, United States. It is a roughly rectangular area centered on West Main Street and Waterbury Green, the remnant of the original town commons, which has been called "one of the most attractive downtown parks in New England."
The Green was the city's first center, with the buildings around it representing all types of uses, from residences to churches to public buildings. Many early buildings were cleared as the city grew and industrialized. Nearby Exchange Place, the junction of the city's streetcar lines, later emerged as a center for retailing. A devastating 1902 fire in that area led to more clearing and rebuilding. In its wake the city's government buildings were moved to a new municipal complex on Grand Street designed by Cass Gilbert, in accordance with the principles of the City Beautiful movement.
Most of its buildings, large commercial blocks, date to the peak years of the city's industrial prosperity, the late 19th and early 20th centuries. A few earlier buildings survived a devastating 1902 fire. Among them works by locally and nationally prominent architects, the latter group including Henry Bacon and Henry Dudley in addition to Gilbert. They include a variety of contemporary architectural styles, particularly the Second Renaissance Revival, Georgian Revival and Romanesque Revival modes.
A historic district or heritage district is a section of a city which contains older buildings considered valuable for historical or architectural reasons. In some countries, historic districts receive legal protection from development.
Historic districts may or may not also be the center of the city. They may be coterminous with the commercial district, administrative district, or arts district, or separate from all of these.
In Canada, such districts are called "heritage conservation districts" or "heritage conservation areas" (known as "arrondissements historiques", "secteurs de conservation du patrimoine" or "districts de conservation du patrimoine" in French) and are governed by provincial legislation.
The United States has specific legislation identifying and giving protection to designated historic districts.
In the United States, a historic district is a group of buildings, properties, or sites that have been designated by one of several entities on different levels as historically or architecturally significant. Buildings, structures, objects and sites within a historic district are normally divided into two categories, contributing and non-contributing. Districts greatly vary in size: some have hundreds of structures, while others have just a few.
The U.S. federal government designates historic districts through the United States Department of Interior under the auspices of the National Park Service. Federally designated historic districts are listed on the National Register of Historic Places, but listing imposes no restrictions on what property owners may do with a designated property. State-level historic districts may follow similar criteria (no restrictions) or may require adherence to certain historic rehabilitation standards. Local historic district designation offers, by far, the most legal protection for historic properties because most land use decisions are made at the local level. Local districts are generally administered by the county or municipal government.
