If you're mad as a hatter you may want to take a trip to Gubbio, the city of mad people (la città dei matti)!
People from Gubbio, a town located in the northeastern part of Umbria are traditionally known for their unpredictable actions.
Do you want to become a licensed eccentric person too? Just go to the Fountain of Mad Men (la fontana dei matti), run round it three times and say "I am crazy" three times. For just a few Euros you can have an official document confirming your insanity! This is an essential document in this day and age.
All madness aside, Gubbio is a wonderful historical city with beautiful palaces, churches and a medieval feel.
