On the porch of the Cathedral of Carinola, an antique Ionic column turned upside-down serves as a base for one of the four columns of the arcade. The porch was built in the thirteenth century, but was restored in the fourteenth, after an earthquake in 1349. The column that stands on the capital is slightly shorter than the others, which have a simple bases. All of the columns carry medieval capitals. The difference in length among the columns may be due to damage sustained in the earthquake, or, as is often the case with spolia, may have been an original characteristic of the building materials.
