So this lift was the former East Cliff Beach (1908) transfered to the current Viking Bay Lift (2000) at Broadstairs after the old Funicular Railway was deemed unsuitable for repairs.
The three Ramsgate lifts were: Western Undercliff, Central (know called East Cliff), and East Cliff Beach (later named Marina when the swimming pool was built in 1935).
From your feature MartinR:
HISTORY: East Cliff or Harbour Lift was built in 1910, the second of three lifts in Ramsgate, but now the older of the two that survive. The earliest, the Marina Lift, which was built in 1908 further to the north on the East Cliff, was demolished after falling into disrepair. The West Cliff Lift was built in 1926: probably designed by Sir John Burnet and Partners, this is listed at Grade II.
