This is so cool

From the bldgblog:

Some new images of the ongoing laser-scan project taking place in the caves beneath Nottingham, England, have been released. "The Nottingham Caves Survey is in the process of recording all of Nottingham’s 450+ sandstone caves," the organizers explain.

From malting caves and circular kilns to a 19th-century underground butcher, via the Shire Hall and, of course, Mortimer's Hole, it's intoxicating to imagine a city whose most exciting discoveries lie somewhere far below its own streets and urban surfaces, in a delirious sprawl of artificially enlarged sandstone caves.

Here's one of the laser-scan images, but DEFINITELY watch the video below for a full tour (sound off).
