No I don't go in there to pray, but I do get down one knee to put the camera on the floor in order to take pictures in frog's perspective.
As a rule French and Belgian roman-catholic churches leave their doors open during the daytime for those in need of prayer or just the occasional visitor like me.
It has become a routine of sorts: see if the door is open, take a quick pic and maybe a look around and out again. That approach has now led to a pleasant collection that you can find in the film strip below.
The image above is St-Bartholomew's church in Geraardsbergen in Belgium.
