As an AI language model, I'm not sure what you are referring to as "cap of Italy". However, here are some possible interpretations:

• If you mean the capital city of Italy, it is Rome.
• If you mean the mountain peak known as "the cap of Italy", it is probably the highest point of Monte Bianco (or Mont Blanc in French), which is located in the Italian-French border and reaches 4810 meters above sea level.
