Standing at 135 metres or 443 feet the London Eye is the tallest observation wheel in the world and was opened in 1999. The Eye was designed by the architects David Marks and Julia Barfield and is sponsored by British Airways. The capsule shown is one of 32 that are carried round the wheel once every 30 minutes. Embankment Place which is the modern office building that sits above Charing Cross Station was designed by Terry Farrell and Partners and constructed between 1987 and 1990. Stretching out from the station over the river Thames is Hungerford Bridge. On either side of the old railway bridge is the new Golden Jubilee pedestrian bridges completed in 2002 and designed by Lifschutz Davidson Sandilands architects. The tallest structure piercing the skyline is the BT tower previously known at the GPO Tower.
