Not only is Amalfi coast one of the most beautiful parts of Italy, it also produces some of the most delicious lemons I have ever tasted in my life. The Amalfi lemon is regarded by cooks as the Prince of the lemons.
They also serve a very important role: With its steep cliffs, the Amalfi coast is susceptible to landslides. The roots of the lemon trees help to stabilise the ground, and the dry stone walls of the terraces also play a crucial role.
Oh, and don't forget to try some Limoncello too when your visit!
