19th-century London - Wikipedia

With the eclipse of the sailing ship by the steamship in mid-century, tonnages grew larger and the shallow docks nearer the city were too small for mooring them. In response, new commercial docks were built beyond the Isle of Dogs: the Royal Victoria Dock (1855), the Millwall Dock (1868), the Royal Albert Dock (1880), and finally, the Port of Tilbury (1886), 26 miles east of London Bridge.Get price
