The city of Charleston was founded in 1670, with its main historic colonial heart laid out in 1680 on the peninsula at the confluence of the
Ashley and
Cooper Rivers. Since that time, the city has been a major commercial and trade center on the southeastern seaboard of North America. Its architecture reflects numerous significant periods of development, with high-quality examples of different architectural styles resulting from the city's continued importance through more than 300 years of history. Significant among these are the many Charleston "single houses", which are typically a single room in depth, and oriented with the short access toward the street, with the entrance area on a long side. These types of houses are built using all types of building materials, including wood, brick, and stucco. In
Ansonborough, there are blocks of fine Greek Revival houses, built in the wake of an 1838 fire. Broad Street, a major east–west thoroughfare since the early days, is home to a fine collection of Federal period houses, many of which have been converted to commercial uses. It is also where a number of important early civic and institutional buildings are located, including the 1752
St. Michael's Episcopal Church, the 1767
Exchange, and the 1792
Charleston County Courthouse. NARA version of "Charleston Historic District" is very different, is missing core documents. Includes maps of 1931 designated (portion which became NHL), of later addition to NHL, and of 1960 designated which was NRHP-listed. Includes correspondence, photos, more. ==Images==
