In 1944 the palace was seriously damaged by air bombardments and was again restored in the immediate post-war era: the external walls to east and north, leaning in a frightful manner, were brought back to the vertical with a new and bold system of winches and steel cables.
Internally the Palazzo has several frescoes diting from the time of its construction to later frescoes of veronese derivation. The coat-of-arms of all the City mayors from 1337 to 1642 are found in frescoes located under the roof truss beams.
The Salone dei Trecento is today used not only by he Consiglio Comunale but also for conferences public debates and art shows.
To the left of the Palazzo dei Trecento stands the Palazzo della Prefettura (Prefecture Palace): its east wing, ex Palazzo Pretorio (Magisterial Palazzo), was renovated last century in the style of Lombardy; its noth wing was completely renovated between 1874 and 1877 by Camillo Boito and engineer Giulio Olivi to replace the Palazzo Comunale. The Civic Tower rises behind, its large bell (called "Marangona") has always bee the announcer of historical events of the City.
Via Barberia begins in front of the piazza one of the most characteristic side streets in Treviso. The street is flanked by face brickwork buildings and a few frescoes (Ca' dei Ricchi is a good example). Open air art shows are often held in this area.

PIAZZA MONTE DI PIETA'

Between the Loggia dei Trecento and the Palazzo della Prefettura, in Piazza dei Signori, is the wind-tunnel called Sottoportico dei Soffioni which leads to the small piazza of Monte dl Pietà.
The name is from the late 15th century when the Monte dei Pegni (or pawn shops) were established above the prisons and where the small church of St. Lucia now stands. This activity can be said to continue today in the Unicredit Bank.
Inside the Cappella dei Rettori is one of the City's artistic treasures. Dating from the middle of the 16th century it is completely decorated: the ceiling's exposed beams are painted; the centre of the back wall is in the shape of a small apse, is covered by a fresco depicting the "multiplication of the fish and loaves" by Ludovico Fiumicelli, under this fresco and along the side walls, runs a splendid group of paintings by the flemish artist Ludovico Pozzoserrato, depicting stories from the Old and New Testaments relating to Charity; and lower down, the walls arte completely covered by precious, giled hides, more commonly used by the Venetians as wall linings but also found in Trevisan houses, by Cordova.
The restoration of this building, like many other in the City, is due to the wise diligence and sensibility of the administrators of the  Cassamarca Foundation.
It was only a some years ago, in fact, that this work of art was brought back to its ancient splendour and opened to the public.
The Piazzetta Monte di Pietà, until a few years ago was known as the Piazzetta dei Funghi (piazza of mushrooms): traditionally, stalls of local mushrooms fill the piazza during the autumn period. However, until last century, it housed the meat market and hence earned the name "Piazzetta delle Beccherie" (piazza of Butchers). A renowned restaurant nearby, in which one can taste and appreciate traditional trevisan cusine, keeps this memory alive.

THE CROSS ROADS

The "Quadrivium" or " croos roads" is the junction of the Roman Cardo and Decumano, roads which determined the orientation and urban development of the City.
Here we find the Loggia dei Cavalieri (the Knights' Loggia). Professor Luigi Menegazzi in his "Treviso Nostra" states that the Loggia dei Cavalieri is unique, of singular lightness and elegance for a Roman structure. In the 1314 Statutes it was defined so: "maxima pars pulchritudinis civitatis Tarvisii".
It was once the place where noble citizens played chess . Today it houses art shows or cultural events.
The Loggia was most probably built when Andrea da Perugia was mayor in 1276-77, the periodo which the oldest frescoes decorating it can be attributed.
Left in an abandoned state for centuries, it was reinstated to its original form in 1911 and again restored in 1945, after being damaged in the second World Warm.
Today it looks like an empty trapezoid open on three sides and with only traces of the frescoes left. Frescoes which originally completely covered the internal and external walls with the coat-of-arm of the Collegio dei Nobili, chivalrous events and geometric and floral patterns.
