The unusual red brick tower looking down Colchester High Street is England's largest Victorian water tower. Completed in 1883, the 116ft building took over a year and half to build. Its cast-iron tank holds 1000 tons of water and it was named after Jumbo, London Zoo's famous elephant. The Tower was decommissioned in 1988, but it's one of the few water towers with good access - a spiral staircase leads to a viewing platform - and it is hoped it will one day be open to the pubic.
