Literature
Here are the books I have used to gather information about the churches and the region.
Les églises fortifiées de la Thiérache - Picardie, Aisne

This short book gives a good overview and is the best choice for occasional visitors of these churches
Les églises fortifiées de la Thiérache

This is the standard work on the fortified churches of the Thiérache, to which all other authors refer
