The Sacri Monti of Piedmont and Lombardy are a series of nine calvaries or groups of chapels and other architectural features created in northern Italy during the late sixteenth century and the seventeenth century. They are dedicated to various aspects of the Christian faith and are considered of great beauty by virtue of the skill with which they have been integrated into the surrounding natural landscape of hills, forests and lakes. They also house important artistic material in the form of wall paintings and statuary. In 2003, they were named as a World Heritage Site.
