Six years ago, the Brighton Eye (akin to the London Eye) was replaced as a seafront landmark in Brighton by the British Airways i360, a 162-metre-tall vertical tower and its observation pod which lords it over the seafront.

It is located opposite the South African War Memorial statue that stands guard by Regency Square and close to the site of the derelict West Pier that was burned down by fire in 2003. You can still see the sad ruins of the beleaguered pier in the water.

Some have dubbed the observation pod the “doughnut” due to its shape, while others have been known to refer to it as something far cheekier (best left unquoted).

Whatever you call it, there is no doubt that the i360 is a huge feat of engineering. You can find out more after the flight at the free exhibition.

This is the world’s tallest moving observation tower with an observation pod built around a central column. It is, in fact, a fully enclosed futuristic glass sphere that gently lifts (the movement is hardly discernible) up to 200 people to a height of 138 metres
