Torre Gattoni

Medieval walls, a teenage scientist and the dawn of urban electrification meet at one corner of central Como. Torre Gattoni entered scientific history around 1765, when the young Alessandro Volta ran his first experiments in the physics cabinet installed here by his friend Giulio Cesare Gattoni. Around 1930 it became the cabin supplying current for Como's lighting, active until 1958.

Why it matters

Volta's genius is usually dated from his Pavia professorship and the invention of the pile, but every discovery has a workshop. Torre Gattoni was his. Giulio Cesare Gattoni — canon, physicist and lifelong friend, whose conversations and shared experiments with Volta are documented in the national biographic dictionary Treccani — fitted out a physics laboratory in the tower, and it was there, around 1765, that the teenage Volta conducted his first scientific trials. The tower therefore marks the exact point where the experimental career of one of physics' foundational figures began. Its second life matters too: as the city's first electric cabin, it connected Volta's science directly to the electrification of the very streets where he grew up.

What to notice

The tower's masonry belongs to Como's medieval defensive system; its later scientific and industrial uses added further layers to the structure's history. The municipal portal notes visible evidence of the electrical chapter: the switchboard with its measuring instruments and disconnectors, and transformers known as "basculla", installed when the tower fed the city's lighting network. Gattoni's scientific installation is part of the story as well — the canon moved his equipped physics cabinet, a rich library and a meteorological observatory into the tower, and the famous electric chimes and conductors associated with his experiments became a local marvel.

Context and history

The tower belongs to Como's medieval defensive system, standing at the crossing of the historic walls near Porta Nuova, and takes its name from the patrician Gattoni family whose house stood nearby. In the eighteenth century Giulio Cesare Gattoni transformed it into one of Lombardy's private scientific hubs: Treccani's biographic entry records the intense intellectual partnership between the canon and Volta — an "indivisible companionship" that lasted until Volta left Como for the University of Pavia at the end of 1778 — and the experiments in physics, meteorology and natural history they pursued together. The famous lightning rod associated with Gattoni's house and then the tower made the site a talking point of Enlightenment Como. After centuries of quiet, the tower returned to usefulness around 1930 as the first cabin supplying electric current for the city's public lighting, a function it kept until 1958, sealing its double identity as both cradle and delivery point of Como's electrical history.
