Medieval churches: sources and forms
Prototype: the ancient Roman basilica
The church plan
An aisle often surrounds the apse, running behind the altar. Called the ambulatory, this aisle accessed additional small chapels, called radiating chapels or chevets. Of course, there are many variations on these typical building blocks of medieval church design. Different regions had different tastes, greater or lesser financial power, more or less experienced architects and masons, which created the diversity of medieval buildings still standing today.
