South End is one of the 21 officially recognized neighborhoods of Boston, Massachusetts. It is an upscale residential, retail, and commercial district. South End and neighboring Back Bay are considered among Boston's most expensive Boston real estate neighborhoods, with townhouses regularly selling for millions of dollars. Popular upmarket shopping destinations include Tremont and Washington Streets as well as the arts district sometimes known as SoWa.
Architecturally the neighborhood and South End real estate are dominated by mid-nineteenth century bowfronts — aesthetically uniform rows of five-story, predominantly red-brick structures, of mixed residential and commercial uses. The most common styles are Renaissance Revival, Italianate and French Second Empire, though there are Greek Revival, Egyptian Revival, Gothic Revival, and Queen Anne style houses, among several other styles. No matter the style, a common palette of red brick, slate, limestone or granite trim, and cast iron railings provide great visual unity.
Today, the South End is listed on the National Register of Historic Places and is a Boston Landmark District. It is North America's largest extant Victorian residential district.
