What is the name of the head of pilgrimage churches that included an isle around the apse that allowed pilgrims to access raiding chapels? This isle was separated from the monks choir with a screen.

Answer 1

The head of pilgrimage churches with a walkway for pilgrims to access radiating chapels without disturbing the Mass is called an ambulatory.

Step-by-step explanation:

The head of pilgrimage churches like Saint Foy featured an architectural element known as an ambulatory. This is a walkway that wraps around the apse, allowing pilgrims to visit and venerate relics that were housed in radiating chapels without disturbing the ongoing Mass in the central area. The ambulatory was typically separated from the monks' choir by a screen or barrier.
