A walking tour dedicated to the secrets of the Bolognese hill. In the monasteries and in the cenobies of the hill the communities of friars who hosted the pilgrims going to the city met, the bishops many centuries later built their villas here, and the great hydraulic projects to bring the fresh water of the hill took place in this wild corner and wooded in the city. Our itinerary touches some of the wonders preserved in this part of the city, where nature and architecture come together in a unique union. The red and yellow colors of the villas, Renaissance churches and medieval cenobies (ancient medieval monasteries) blend with the light yellowish and white colors of the badlands and clay. Large wooded gardens are the setting for these architectural wonders.
