Art and Monuments
The Scaligero castle towers overlooks the Mincio valley from the summit of the hill, maintaining the majestic effect of the medieval fortifications. From its oldest part, which was almost entirely destroyed in the earthquake of 1117, only the Tonda Tower remains, a horseshoe bat shape construction from the 10th century .
The rest of the complex dates back to the 14th century. Three rising bridges where added, of which only one remains. In July and August the internal courtyard becomes a stage for the summer cutlture and cinema shows.
In Borghetto the Visconteo bridge dominates the scenery, an extraordinary dam built in 1393 at the will of Gian Galeazzo Visconti, the Duke of Milan, in order to guarantee the impenetrability of the eastern borders of the Duke's land. At 650m long and around 25m wide, with a road 9m above the water level below, it is often referred to as the ‘Long Bridge'. Finished in 1395, after only two years of intense work, it connects to the towering castle through two tall crenelated sheets and is integrated into a fortified complex called the ‘Serraglio', which extends for rougly 16km, up to Nogarole Rocca.
 
Also in Borghetto the small Church of San Marco the Evangelist can be visited. Dedicated to Saint Maria and built in the 11th century, it sits on the remains of a Roman parish church. In the vicinity of the little San Macro Bridge, in front of the church, a statue of S. Giovanni Nepumoceno is cast in the walls of an old house. The tradition suggests that this statue protects those who fall in the river from drowning.
The church of Saint Peter's Chair, in the centre of Valeggio, was erected in 1753, on the remains of a church from around 16th century, but there are documents that prove the existence of a roman church from 1145. Inside the church, whose façade is incomplete, a large neoclassic nave brings one's attention to the huge alter from the 19th century; whilst above the entrance doorway, one can admire a large fresco from the 18th century, displaying the hunt of the merchants from the temple. On the lest, a magnificent cane organ from G. B. Sona from the Venitian-Gardesana school of the 18th century is completely restored and functioning.
 
In the historic centre, on via Murari, the 18th century Palazzo Guarienti can be found: in rigorous neoclassical style, more severe than elegant. On the façade a plaque remembers the evening of 30th May 1796, during the campaign of Italy, when Napoleon Bonaparte, who was staying in the Pallace, risked being captured by the Austrians, who appeared unannounced in the town.
On the right hand side is another plaque, dedicated to don Giovanni Beltrame, a missionary, an academic and an explorer from Valeggio in the centenarian of this death (1906).
 
The Villa Maffei Sigurta, the luxurious summer home of the Counts of Maffei, gentlemen of Valeggio and Monzambano from 1649, was designed and built by the architect Vincenzo Pellesina (1637-1700) who was inspired by the more famous projects of the Paladium. His style is testament to the transition from Baroque to the more clean neoclassical. In the gable, above the loggia fresco, a plaque remembers the old investment of the Maffei.
At the back of the Villa, in the old ‘brolo', the Sigurtà park extends: it was acquires in the 40s by the Count Dr Carlo Sigurtà, and he transformed it, after years of passionate work, into one of the most beautiful botanical sites in Europe. The park is open to the public from March to November.
