Four bridges over the Reno
A long zigzag on the most important waterway of Emilia Romagna, discovering bridges and places of unsuspected historical and architectural value.
It starts from the spinning mill and immediately crosses the first bridge, beyond which the Garibaldi district develops. Traveling along via Tripoli and then via dello Sport and via dei Mille, you will find the Blogos Youth Center and the town hall. Then take the Ponte della Pace , a magnificent cable-stayed structure, until you get to Romainville, a park and sports area so called for the twinning with the homonymous French town. You pass under the bridge itself, walking along the river until you get to the bridge over the Rhine (via Porrettana). You also go along the latter and soon you arrive at the Piazza del Monumento ai Caduti ; from here starts a comfortable walkway that reaches the Lido di Casalecchio .
A narrow road takes us to via Ronzani which you must follow for about 800 meters, when a sign indicates the deviation for the walkway. The return takes place through the Parco della Chiusa to San Martino ; then follow the cycle path towards Bologna until you return to the starting point.

The Ice House
The Scaletta Paraporto is also part of the complex artificial hydraulic system of Bologna and its province, also called "The Ice House", inaugurated after the renovation in May 2009. Today it is an important
point of the tourist route to visit the Bolognese waters. In the past, an iron grate, still visible, was lowered into the water to prevent the ice sheets that formed in the coldest months from ruining the wheels of the mills and factories that worked thanks to the driving force of the canal water. Today the plant mainly prevents the accumulation of the various materials transported by the water, performing a cleaning function. The architect of the building was Jacopo Barozzi called "Il Vignola" who, in the mid-16th century, intervened on a pre-existing plant, probably contemporary to the birth of the canal (around the year 1000). 
In 1851 a group of noble and wealthy Bolognese bourgeois, including Minister Marco Minghetti and Conte Zucchini, built a large and modern factory for the processing of hemp in Casalecchio di Reno, in the Canonica area, incorporating pre-existing buildings used as a factory. paper, oil refinery, etc. The canapificio was, at the time, one of the first in Italy for size, machinery and financial availability. The original structure was gradually enlarged, especially after 1906, when the Linificio e Canapificio Nazionale purchased the factory from the ancient owners. From the start of production to 1910, the factory operated exclusively on hydraulic energy, obtained by exploiting the water jump from the canal. The development of the business suffered a setback during the First World War, and then resumed with renewed energy after 1918. With the hemp crisis and the 1929 earthquake, the plant began to decline: given the serious damage, the property decided to move production to its other factories, while the definitive closure of the Casalecchio di Reno plants was decreed. The building was then made available to the military authorities. With the armistice of 8 September 1943 the Barracks of the Bastia emptied themselves of the fleeing military and was sacked by the population who, in a single day, made food, furniture, weapons, horses and means of transport disappear.
