Boston's South End, built on mostly man-made land, had become the city's premier neighborhood by the 1850s and featured many parks embellished with cast-iron fountains and distinctive fences. Over the next century, the South End became a thriving melting pot of ethnicities, races, and religions. Boston's South End shows how this area's brick row houses, lush green parks, upscale restaurants, and Boston Center for the Arts have made the South End both an attractive destination and a popular residential area.
