Geograph is a concept and open source code for a online website to create a comprehensive collection of photographs capturing every part of given region.
Currently there are three active projects, shown below - including a photograph from each.

This part of Holy Island is largely uninhabited. The exception to this is Snook Tower, hidden amid the dunes and possibly built in the early 1800s as a lookout tower.
