A Day Trip exploring Pietravairano and the Temple in the Clouds. Teatro Tempio San Nicola was discovered only due to a brush fire in 2001, and the rest is history! Pietravairano is a small town in the Campania region with plenty to do for a lovely day trip. There is a castle, a temple, beautiful churches, a historic neighborhood, and a great restaurant, La Caveja. Well worth the trip!
