Construção
The Sanctuary of the Madonna of San Luca is a basilica church in Bologna, northern Italy, sited atop a forested hill, Colle or Monte della Guardia, some 300 metres above the city plain, just south-west of the historical centre of the city.While a road now leads up to the sanctuary, it is also possible to reach it along a 3.8 km monumental roofed arcade (Portico di San Luca) consisting of 666 arches, which was built in 1674–1793.
