This Google Earth flyover, developed by Daniel J. Wilcox, explores key points on the Clerkenwell Commons trail. We'll add on-the-ground-video to the popups, and a voice over. We are also exploring how to add some historical images.
See the Clerkenwell Commons trail page for a map of places to explore on the ground, and the gallery for detail about each point, including some now and then images. The slideshow contains images from the trail.
