Casting a protective eye over Bologna, the hilltop Santuario de Madonna di San Luca basilica can be seen from most vantage points in the city.
Built in the mid-18th century to house a portrait of the Virgin Mary painted by St Luke, the basilica has some notable artworks and statues.
One of the main highlights of this basilica is getting there – on foot. The sanctuary lies 4 km (2.5 miles) south-west of central Bologna, linked by the world’s longest undercover portico. Supported by 666 graceful arches, the portico is gently stepped as it winds uphill.
