Torre Alberti

Bormio preserves an unusual number of its medieval houses, and one vertical fragment of the noble town stands out among them: the Torre Alberti, a grey stone tower of the thirteenth century on the pedestrian stretch of Via Roma, the surviving upright of the Alberti family's fortified seat.

Why it matters

Bormio preserves a notable group of medieval houses, among them the Torre Alberti. Roughly twenty to twenty-five thirteenth- and fourteenth-century dwellings survive in Bormio. The tower is a surviving part of the fortified compounds around the main square; it is classified as defensive architecture and remains a private residence. It reflects the wealth and defensive concerns of Bormio’s medieval families.

What to notice

The tower rises about twenty-four metres and is built of exposed grey stone; it dates to the thirteenth century. Narrow pointed openings and massive corners reflect its defensive design. It is known as the Torre degli Alberti, in the historic quarter of Dossiglio. Local tradition also knows it as Torre Marioli or Torre di Dossiglio.

Context and history

The tower belongs to the story of Bormio's governing families. The area immediately behind the main square, bounded by Via Alberti, Via al Castello and Via Ripa and facing towards Palazzo De Simoni, was the fortified compound of the Alberti, one of the noble houses that dominated the medieval commune. A Bormio land register of 1304 records an Alberti family tower in this part of town; the great families first competed to raise the tallest and strongest towers, then added their palaces beside those fortifications between the fourteenth and sixteenth centuries. The Viscontean raid of 1376 badly damaged the castle of San Pietro above the town; the Marioli later lived in the palazzo beside the tower. In summer 1496, Duke Ludovico il Moro of Milan arrived in Bormio with his wife Beatrice and court and was hosted by Nicola Alberti in the tower of Dossiglio. Bormio's fourteenth- and fifteenth-century flowering as a commercial crossroads between the Valtellina, the Engadine and the passes to the north created the wealth that such buildings express, and the town's stubborn retention of autonomy under successive rulers kept its old centre intact.
