What were the architectural elements of the basilica plan and the central church plan?

The basilica plan features a rectangular layout with a central nave flanked by side aisles, often culminating in an apse at one end, and may include a transept to create a cross shape. Architectural elements commonly include tall columns, a clerestory for light, and a raised platform for the altar. In contrast, the central church plan typically emphasizes symmetry and geometric shapes, such as circles or squares, often with a dome above the central space. This design focuses on directing attention towards the altar, usually located at the center of the structure.
