indoor activities in naples

coming to naples next week on the 12th then leaving on the 15th and the weather app is showing that its raining on basically all days we are there 🫠

Most of our trip is doing the basics - pompeii, vesuvius, going around the amalfi coast etc but now we might need to rethink about it because of the weather. Do you guys have any recommendations for indoor activities in case these activities aren’t viable?
