Here is a short list of funny, strange, or interesting laws in Italy that, for all I know, we do not have in the United States.  I don’t know the origin of these laws, nor the details or definitions.  And I don’t know if these laws are enforced or enforceable.
• In Milan a law states that locals must constantly smile or risk being fined.  Those attending a funeral or visiting a hospital are exempt.
• It’s against the law in Florence to eat or drink in the immediate vicinity of the main churches and public buildings.
• The Supreme Court of Cassation ruled that it is legal for anyone living in Italy to grow marijuana from balconies or terraces.
• A few years ago the Italian Supreme Court ruled that having sex in a car that is parked in a public place is a felony, carrying a possible prison sentence of 3 months to 1 year.
• In the coastal town of Eraclea (Veneto), building a sandcastle on the beach is prohibited since it might obstruct the passage of someone strolling on the beach.
• Turin has a law that requires dog owners to walk their poochies at least 3 times a day to avoid a fine of 500 euros.  It is also against the law to “turn one’s dog into a ridiculous fluffy toy”.
• When a vendor or shop owner gives change to a customer, it is never handed directly, but rather always laid on the counter or put in a receptacle on the counter.
• It is against the law to feed the pigeons in St. Mark’s Square in Venice!
• In Naples dog poop samples are tested and then matched to a DNA database.  Owners who do not clean up after their dogs are fined 500 euros.  How ironic in a city with huge garbage problems!
