why does colosseum have holes?

The Colosseum, an iconic symbol of Rome and Roman architecture, has numerous holes and cavities on its surface, which are the result of various historical and natural factors. These holes are mainly due to the extraction of building materials and erosion over the centuries.

In earlier times, the Colosseum was covered with travertine, a type of limestone. During the Middle Ages and the Renaissance, many of the stones were removed to be reused in other constructions, such as churches and palaces. This process of spoliation left evident marks, creating holes and cavities in the structure.

In addition, erosion caused by weathering, such as rain and wind, has contributed to the deterioration of the stone over time. Earthquakes, in particular the one in 1349, have also affected the stability of the Colosseum, causing collapses and further damage.

Today, these holes not only tell the story of the monument, but are also the subject of archaeological studies and conservation, as experts seek to preserve and restore this extraordinary testimony to Roman history.
