The magnificent complex of the Cathedral of Siena, its Duomo, houses a series of some of the most important monuments of the European artistic panorama. With its more than one million visitors every year, the Cathedral without a doubt represents the fulcrum of the entire complex, while other significant elements include the Crypt, the Baptistery and the Museo dell'Opera, all part of the impressive mass formed by the "Duomo Vecchio" (Old Cathedral), and the "Duomo Nuovo" (New Cathedral). Visitors will travel along a memorable itinerary to the discovery of self and the truth of faith through culture and art, the result of more than a millennium of Western history.


The magnificent façade of the Duomo, as the Cathedral is called, is flanked by two majestic towers ending in many spirelike forms that shoot upwards. In these towers, winding staircases, practically invisible to visitors, lead up to the ‘heavens’ of the Cathedral. Above the starry vault of the right aisle begins an itinerary reserved to small groups accompanied by expert guides, which reserves a succession of discoveries and emotions. Visitors will indeed walk ‘above’ the holy temple and admire fascinating views both ‘inside’ and ‘outside’ the Cathedral. From the polychrome stained glass windows depicting the Apostles by Ulisse De Matteis, visitors will gaze down onto the floor and the principal sculptural monuments, and even inside the dome with its ‘Pantheon’ of Sienese saints, the four Patron Saints, Saint Catherine and Saint Bernardino, the golden ‘giants’ who from above protect the community of the faithful. Then, from the balcony of the dome, they will contemplate the high altar, the copy of the stained glass window by Duccio di Buoninsegna with, in the centre, the mandorla of the Assumption of the Virgin Mary, and masterpieces of sculpture. From the left aisle, they will look out to admire a splendid panorama of the Basilica of San Domenico, the Medici Fortress, the entire dome of the Chapel of Saint John the Baptist, and the surrounding countryside up to hills known as the Montagnola Senese. Finally, they will enter behind the façade, at the balcony that looks out onto Piazza del Duomo and the view of the Spedale di Santa Maria della Scala, and enter the balcony on the counter-façade. Here unfolds an overall view of the nave; the gaze scans the heads of popes and emperors, the intarsias with the philosophers of the ancient world uttering sentences. The “gate of heaven” is opened to visitors as though they were climbing the ladder that appeared to Jacob in his dream, the top of which reached heaven, and the angels of God ascending and descending on it (Genesis 28: 10-22). In his dream, God promises Jacob the earth on which he has slept and an immense lineage. When he rises, Jacob exclaims «This is none other but the house of God, and this is the gate of heaven», a verse used by the liturgy of the mass in dedicating cathedrals. In the Litany of Loreto, though, the ‘gate of heaven’ is also the Virgin Mary, a definition that best expresses her power and goodness. As the Mother of Christ and of humanity, Mary contributes to our eternal salvation in Heaven where she is the ‘Queen assumed into Heaven’. The visiting itinerary “from above” will thus permit visitors to better understand the dedication of the Cathedral of Siena to the Assumption of the Madonna, and the strong connection the people of Siena have had with their ‘patron’ for centuries: Sena vetus civitas Virginis.

Strongly desired by the Opera della Metropolitana di Siena, the initiative is organised by Opera – Civita Group.
