Step-by-step explanation:
The architectural plan of San Vitale in Ravenna relates to both the basilica-plan and central-plan type churches. The basilica plan is characterized by a long axis focusing on the altar, while central-plan churches have a central dome surrounded by an ambulatory. San Vitale incorporates elements of both types, with a central dome surrounded by two ambulatories. This makes it a prime example of an Eastern, centrally planned church.
