London Eye

The London Eye was opened for business at the turn of the 21st Century, and is the world's tallest observational wheel, with a height of around 135 m. It affords magnificent views over London, and attracts around 10,000 visitors per day, though some patience is required while waiting in the queues to get onto it!

And as seen from directly underneath it

You get a good view of London from the Eye

I believe it takes about 30 minutes to complete one revolution

I've never been up in it, but maybe one day ...
