On one of Bologna’s most picturesque hills stands a place frozen in time and closed for 80 years: the Malvasia Meteorological and Seismic Observatory, near the Sanctuary of the Blessed Virgin of San Luca on Colle della Guardia, which will reopen to the public on October 31. The National Institute of Geophysics and Volcanology's significant research and restoration effort has recovered unique scientific equipment, which will be returned to some of the areas where they were initially housed after nearly a century. Among the instruments that will be revitalized are the renowned Malvasia Seismic Warning Device and the Denza Anemograph, which are testaments to the exceptional quality of scientific research in Bologna and Italy during the late 19th century. Count Antonio Galeazzo Malvasia della Serra founded the Observatory, which opened on November 14, 1881, following an earthquake in the Bologna area earlier that year. It operated successfully until the 1940s. After that, the Observatory was permanently deactivated, and much of the apparatus stored there, which was among the largest in Italy at the time, was lost. Today, it has been rediscovered.
