This is an attempt at creating a crowd-sourced interactive map of all the roadside Shrines and Grottos in Ireland captured by Google Street View. If you know of a site that is not on the map, please add it by clicking the 'Add Shrine' at the top right of the page.
This site was hacked together quickly, if you have any sugestions (or spot any bugs) do get in touch.
If you still want to know more there is a blog post here which might be of interest.
