The museum contains the only surviving original telescopes built by Galileo Galilei.
Galileo's middle finger is on display, encased in a glass egg, alongside a tooth and a vertebra.
The 1593 armillary sphere created by Antonio Santucci is one of the largest and most complex ever constructed.
The collection includes a massive 17th-century 'thermometer' that uses individual glass bulbs to represent temperature increments.
The building itself, Palazzo Castellani, served as the seat of the Accademia della Crusca, the oldest linguistic academy in the world.
Many instruments on display were personal items used by the Medici family for scientific study and demonstration.
The library holds over 150,000 volumes, including rare editions of scientific works from the 16th century.
Museo Galileo, housed in the 11th-century Palazzo Castellani, holds one of the world's most significant collections of scientific instruments. The museum preserves the original objective lenses used by Galileo Galilei to discover the Jovian moons in 1610. The collection spans from the Renaissance to the 19th century, featuring astronomical, mathematical, and navigational tools. Central to the exhibition is the original telescope and the 'celestial globe' crafted by Antonio Santucci in 1593. The display includes the physical remains of Galileo, specifically his middle finger and a tooth, retrieved during the relocation of his body in 1737. The museum emphasizes the evolution of observational science through artifacts commissioned by the Medici and Lorraine grand dukes. Multimedia stations throughout the galleries provide interactive context for the mechanical precision of the antique machinery. The facility serves both as an exhibition space and a specialized research library for the history of science.
The central staircase of Palazzo Castellani offers a high-contrast view of the historic architecture blended with modern museum signage.
Use the museum's provided tablets or interactive displays to see zoomed-in digital recreations of how the antique instruments functioned.
Focus on the Medici collection on the ground floor before moving to the Lorraine-era advancements on the upper level.
Check the digital interactive map available on the museum website to identify specific instruments before your visit.
Do not rush through the ground floor; the most significant historical artifacts, including Galileo’s own work, are concentrated in the early galleries.
Open daily, but frequently closes on specific public holidays; check the official calendar for potential closures during the winter months.
Maintain a quiet volume and do not touch the glass display cases; flash photography is generally prohibited to protect sensitive historical surfaces.
