La Specola, is a site that offers a journey through its millennial past with 250 years dedicated to astronomy. This grand structure, which includes the Torlonga, was a medieval defensive tower erected in the 9th century AD, it changed its use over the centuries—also serving as a prison and undergoing modifications to adapt to these functions. Its transformation into an astronomical observatory took place at the end of the 18th century, when the Republic of Venice authorized its use by the University of Padua. Considering this new function, a reconstruction project was initiated. A significant inscription marks the rebirth of the building: “This tower that once led to infernal shadows, now under the auspices of the Venetians opens the way to the stars.” The observatory had a Sala Meridiana, dedicated to measuring the local noon time, and a Sala delle Figure, an octagonal room designed for more extensive observations. The latter was adorned with frescoes depicting famous astronomers. Over time directors of the center continued to modernise the equipment and the structure, adding new halls for advanced telescopes, such as the prestigious Merz refractor.
