Step-by-step explanation:
The novel feature of some French Romanesque church plans that is designed to facilitate the circulation of pilgrims is known as the ambulatory. This element takes the form of an aisle around the central space or apse in a pilgrimage church, allowing easy access to the radiating chapels that house relics.
Pilgrims could move through the church and venerate the relics without disrupting services. in the architectural planning of these churches, the ambulatory provided a way for pilgrims to visit each chapel consecutively, ensuring a smooth flow of traffic and enhancing the pilgrim’s experience. This design was essential for managing the large crowds that visited these religious sites.
