How well do you know the landmarks of London? Get up close and personal with a stunning 320-gigapixel image of the city captured atop the BT Tower.

Snapped by panorama experts 360Cities, the epic photography endeavor required the use of four Canon 7D dSLR cameras outfitted with some heavy-duty equipment.

Each camera used an EF 400mm f/2.8L IS II USM lens, Extender EF 2x III teleconverter, and a Rodeon VR Head ST robotic panorama head. After shooting 48,640 individual pictures over the course of three days (shortly after the 2012 Olympics), 360Cities spent the next several months assembling and stitching together the final gargantuan image.
