Cathedrals are places of worship that are the central church of a diocese or an archdiocese. They are usually larger in size than a basilica and have a more ornate design. Cathedrals often feature high ceilings, intricate stained glass windows, and large spires. Basilicas are also places of worship, but they are usually smaller than cathedrals and have a simpler design. They may have some decorative elements, but they are not typically as ornate as cathedrals. Both cathedrals and basilicas are used for religious ceremonies, but cathedrals are usually used for more formal occasions such as ordinations and consecrations.
