Across the roundabout from the fountain you’ll see a white building with a tall tower. This was the Casa del Fascio, the Fascist HQ in Trento. At the base of the tower you’ll spot a relief of a fascist solder, one hand raised in a Roman salute. On 8 September 1943, when Italy surrendered to the Allies, the Germans occupied Trento and the building became the Nazi command centre. ‘The Fascist City’ trail takes you here on this fateful day, one that changed the course of WWII.

The Piazza del Duomo was a theatre of power in the Renaissance. Fireworks and artillery thundered to mark royal entries or the proclamation of a new Holy Roman Emperor. But the square also pulsed with everyday life, packed with market shoppers, foreign merchants, town criers and beggars. Explore it in 1520 with Ursula, in 'Innkeepers, princes and migrants', and with Angelo in 'City of the Council', set in 1563: two of the audio trails in the free Hidden Trento app. Tap find out more.

The Tower in the Piazza, now a museum, spoke to Trentini of civic power. From the 13th century its bells dominated Trento's sonic landscape. By the 15th century the city's ryhthms were further marked out by the addition of the tower's first mechanical clock. Around the same time it became the city's jail, and remained so until the 1700s. Inside, traces of graffiti carved by the condemned are still visible. Find out more in Ursula's 'Innkeepers, princes and migrants' audio trail.

In Piazza Pasi, once called the Piazzola, you'll spot frescoes on the facade of a tall white palace beside Pasi bar. On the left, San Rocco, with his staff and dog. On the right San Sebastiano, punctured by arrows. These are images of plague saints, commissioned by the palace owners, the Bernardelli - a painted prayer for divine protection from epidemic.

After the great plague of 1630, the remains of Trento's patron saint San Viglio were rehoused in a silver casket to mark the city's deliverance. Still paraded every year on June 26, you'll find this stunning civic symbol at the Museo Diocesano Tridentino. It's just one of the museum's treasure trove of objects, paintings and statues featured in 'City of the Dead' and 'Sword and the Cross', two free audio trails that transport you back to a dramatic day in December 1658.

The woman above the archway, created in 1937, is one of the most prominent traces of fascism in Trento. She marches in victory, holding the fasces that symbolised the dictatorship, while beneath her Mussolini’s words mark the conquest of Ethiopia. After WWII the fasces and Mussolini’s name were removed. The archway leads into the Piazza del Littorio (now Piazza Cesare Battisti), a new heart for the city built in Fascist style. ‘The Fascist city’ trail puts you here in 1943. Tap find out more.

The body of Christ was raised twice in the church of San Pietro, since mass was celebrated by both a German and an Italian priest. With its pointed, German-style belltower, San Pietro was the spiritual hub of Trento's migrant community. It also once housed the tomb of child 'martyr' Simonino, whom authorities claimed was sacrificed by the district's Jews in 1475, a classic example of an anti-Semitic 'blood libel'.

Inn signs, such as this one at what is now the Due Mori trattoria, were once common in the district of San Pietro. Taverns such as the Serpent, the Cross, the Crown, the Sun and the Rose clustered here, largely run by the German migrants who had made this neighbourhood their home. On any sixteenth-century evening you'd find travellers, drinkers and gamblers inside, and perhaps entertainment by minstrels or buffoons.

Buonconsiglio Castle, now the Provincial Museum, was for centuries the power base of the Prince-Bishops of Trento. Modernized in the 16th century, with frescoes inside and a magnificent loggia added at the front, it was where the prince-bishop entertained kings, princes, and cardinals. As the menu for a banquet in the loggia to mark the close of the Council of Trent extravagantly attests, they knew how to throw a party here.

The Raffaelle Sanzio school, completed in 1934, was a pioneering piece of fascist civil architecture. It mirrors the bastions of the old Buonconsiglio Castle next door, but in a radically modernist style: a new building in which to forge new fascist citizens. In ‘The Fascist city’ trail, set in 1943, this is Emma’s school, and she recalls her experiences as a Piccola Italiana, or Little Italian, the paramilitary organisation that schoolgirls had to join under the regime.

"Death conquers all. There are none so rich, wise or strong that they don’t fall down at the feet of Death.” So reads the 17th-century tomb slab to the left of the door at San Marco, one of many under the portico here. Even for wealthy families buried inside the church, death was seen as the great leveller, and it never felt too far away in an age of plague epidemic.

Piazza Dante, with its statue of the poet, is right beside the train station. The station itself is a Fascist creation, and from the piazza you’ll also spot the circular monument to Cesare Battisti, on the hill across the river. Battisti fought the Austrians in WWI to return Trento to Italian rule, and in the 1930s the regime built this mausoleum in a bid to turn him into a symbol of a united Italy under Mussolini. ‘The ‘Fascist City’ trail transports you to this spot in 1943.

The final, crucial sessions of the Council of Trent were held at Santa Maria Maggiore in 1562-63, their goal to oppose the Lutheran heresy and thrash out Church reform. Bishops and ambassadors from nations across Europe quarrelled fiercely - almost as fiercely as some of their trigger-happy followers in the piazza outside - but they finally agreed a set of decrees that set up the basic shape of Catholicism for centuries.

The frescoes on the exterior of Palazzo Geremia depict Maximillian I, the young Habsburg prince declared Holy Roman Emperor in Trento in 1508. This was one of the ways Trento's nobility demonstrated their loyalty to the empire as they upgraded their palaces, on the city's most salubrious street, with Renaissance-style facades and decorations.

Many palaces were rented out to foreign dignitaries during the Council of Trent. Palazzo Roccabruna became home to the Count of Luna, the Spanish ambassador. Luna died in 1563 after drinking and dancing too much at a party, indulging in the local wine, abundant and cheap, that flowed freely during the Council. As chance would have it, today’s Palazzo Roccabruna houses the region's official enoteca, dedicated to promoting food and wine. Find out more in Angelo's 'City of the Council' audio trail.

In the sixteenth century, the road from the Tre Portoni, the Three Gates, was very different. Orchards, gardens, vineyards and trees flanked it as you walked to the Palazzo delle Albere. The prominent Madruzzo family, prince-bishops of Trento, designed the villa and land around it as a 'place of delights'. In effect it was a farm. Water courses irrigated the fields and fed the fish ponds in the moat that once circled the villa. Find out more in Angelo's 'City of the Council' audio trail.
