Have you been to the top of the Clock Tower yet? A visit to the observation deck in the Brisbane City Hall Clock Tower has been a 'must do' for visitors over the last seventy years. The tower rises 92 metres above the ground and access is via the beautifully restored lift to the left of the main foyer. The lift travels through the clock workings. This presented a challenge for the makers who had to install four separate movements for each of the clock face.
