The Facade and Bell Tower

The cathedral sits on the point the locals call Il Poggio — the very summit of Montalcino — overlooking a small piazza. Its imposing facade is dominated by a pronaos of six Ionic columns with marble capitals, surmounted by an entablature carrying the Latin inscription "NON EST IN ALIO ALIQUO SALUS" ("In no other is there salvation," from Acts 4:12). A triangular pediment crowns the composition, and a colored-glass lunette window depicting Christ blessing fills the upper center. Three portals below mark the building's division into three naves. To the left of the facade, the slender bell tower rises in elegant sobriety; it was added in the 18th century using stone blocks taken from the demolished Romanesque church of San Pietro in Asso.↗↗↗

What to See Inside

The interior is a masterclass in Neo-Classical restraint — three barrel-vaulted naves divided by tall Ionic colonnades, decorated in a prevailing white-and-gold palette that gives the space an almost temple-like serenity. The high altar, designed by Fantastici himself around 1828, is a layered composition of colored marbles forming an ideal Ionic temple with a relief of the Lamb of God, flanked by candle-bearing angels.↗↗

For art lovers, the standout work is Francesco Vanni's Immaculate Conception with Jesus and God the Father (1588), a youthful masterpiece showing the influence of Federico Barocci in its figures and a Flemish-inspired landscape behind. Across from it hangs Vanni's earlier Saint John the Baptist in the Desert (c. 1585). In the Chapel of Suffering, accessible from the sacristy, a late-16th-century Sienese painting of Saint Michael driving the rebellious angels from Paradise derives its composition from Beccafumi. In the sacristy itself, a 1647 Assumption of the Virgin by Francesco Nasini depicts Saints Hippolytus and Cyprian.↗↗

The Baptistry chapel at the start of the left nave holds some of the cathedral's oldest treasures: reassembled fragments of an 11th-century alabaster or travertine sculpture showing Christ in a mandorla between two angels with thuribles — relics of the original Romanesque portal destroyed in 1817. A large travertine baptismal font by Egisto Bellini (1933) stands at the center of the chapel.↗↗↗

In the nave's end niches, stucco statues of Saint Michael Archangel and Saint John the Evangelist (1842) by Antonio Rossi add a sculptural punctuation to the white columns. Above the west transept's left arm, the organ by Nicomede Agati (1858) remains a prized historic instrument with fully mechanical action.↗

Kounellis's Caleidoscopio and the Poggio

Step outside the cathedral and cross the grassy area beside it: you'll find a 16th-century stone well that conceals one of Montalcino's best-kept artistic secrets. Caleidoscopio, an installation by the Greek-Italian master Jannis Kounellis, was created for the Arte all'Arte contemporary art festival. Looking through the well's openings, colored-glass kaleidoscopic fragments shimmer in the depths below — a startlingly modern counterpoint to the Neo-Classical temple behind it.↗

The surrounding Poggio also holds the Bishop's Palace (Palazzo Vescovile), built in 1625 by Bishop Ippolito Borghesi, whose noble crest still marks its entrance. This entire quarter, at the town's highest point, was the nucleus of medieval Montalcino and remains its most atmospheric corner.↗

Visiting

The cathedral stands at the top of Via Spagni, at the highest point of Montalcino's compact old town. It is freely accessible during services and typically open to visitors during daylight hours, though hours may vary. Note that the entrance involves steps and the building is not fully wheelchair-accessible.↗

Montalcino is a 40-minute drive south of Siena, perched between the Orcia and Asso valleys in a landscape of cypress-lined roads and vineyards. The cathedral's position at the Poggio means that on clear days, glimpses of the Val d'Orcia's undulating hills can be caught from the piazza outside — a fitting reward after a visit inside. Pair a stop here with a walk down to the Fortress of Montalcino or a wine tasting of the town's legendary Brunello.
