Galileo's Observatory Residence Is For Sale In Florence

Located in the heart of Florence’s hilly Oltrarno district, this prestigious family home stands out for its historical significance. In fact, it is a building adjacent to Galileo Galilei’s home from the first decade of the 17th century: from its tower—which offers an exceptional view—he observed the night sky through his telescope, continuing his studies, which would later prove revolutionary for the history of science.

This property benefits from a quiet residential atmosphere, sheltered from the tourist bustle, yet is located just 300 meters from the Ponte Vecchio and a short walk from the Giardino Bardini, one of the city’s most charming green spaces. The proximity to Forte di Belvedere, which overlooks the street from above and regularly hosts internationally renowned art exhibitions, lends the area an aura of exclusivity rarely found in European historic centers. Costa San Giorgio preserves the legacy of centuries of illustrious residences and continues to represent the iconic address of elite Florence.

The elegant entrance opens onto a corridor that immediately leads to the 330-sqm west-facing private garden. This outdoor space, ideal for intimate dinners and entertaining, includes a covered lounge area, a fully equipped barbecue area and stone steps leading to the main garden. Two spectacular panoramic roof terraces — where, according to historical sources, the scientist Galileo Galilei used to conduct his astronomical observations — now offer 360-degree views of the city, embracing the Arno, the Cathedral, Palazzo Vecchio, Santa Croce and the Forte di Belvedere. A discreet technical room completes the outdoor space.

The ground floor features a sitting room, a private gym, a functional kitchen overlooking the lower garden terrace, and a refined cloakroom. The interior spans 642 square meters across three levels. The first floor is entirely dedicated to entertainment: a large triple living room with a fireplace area invites relaxation, while connected areas dedicated to games and TV add versatility to the spaces. A formal dining room, flanked by a two-level kitchen with breakfast area, pantry and laundry room, is the heart of the living area, completed by a guest bathroom.

The second floor houses the master suite at the rear, a haven of comfort with two bathrooms, a walk-in wardrobe and a private study, ideal for those who need an integrated professional space. The four additional bedrooms are located at the front: two with en-suite bathrooms, the other two sharing a bathroom. All rooms are accessible via internal stairs or a private lift, ensuring fluid vertical circulation throughout the property.
