This 15.5 giga-pixel capture (click through) of the inside of St Paul's has been doing the rounds for a few months now, though somehow we missed it until now. It's stitched together from 2,400 images from a 3.5 hour photoshoot. The results are eye-popping.
The panorama was put together by Spherical Images, a company that specialises in wrap-around photographs. They've got plenty of other 360 degree views of London to play with, including the Olympic velodrome, Wilton's Music Hall and the Lloyds Building, although the St Paul's piece is their richest yet.
Bang up to date, their latest creation is a 360 degree, zoomable capture of the Peckham post-it-note wall, set up after the riots. Click through to play.
