Sanctuario di Madonna di San Luca

Construction of this church was started in 1741 and this was place for women who wanted to spend their life in prayer. Now, it is a the end point of the longest covered portico (the Portico di San Luca), which stretches about 2.4 miles from the city to the hilltop sanctuary. This portico features 666 arches, making it the longest in the world. Pro Tip: Take a taxi there, then walk home. Down the hill (and steps) is much more enjoyable that up!
