By 1694, the public landing built at the head of the Thames River allowed ships to unload goods at the harbor; the harbor area is known as the Chelsea neighborhood. The distance from the port to Norwichtown was served by the East and West Roads which became Washington Street and Broadway. The original center of the town was a neighborhood now called Norwichtown, an inland location chosen to be the center of a primarily agricultural farming community. By the late 18th century, shipping at the harbor became far more important than farming, especially when industrial mills began manufacturing on the three smaller rivers. By the early 19th century, the center of Norwich had effectively moved to the Chelsea neighborhood. The official buildings of the city were located in the harbor area, such as the city hall, courts, and post office, and all the large 19th-century urban blocks. The former center is now called Norwichtown to distinguish it from the current city.
