What about Early Astrophysics's Cradles Today?

Many astronomical observatories where early astrophysical research was carried out have lost their original site or have changed their use. In Europe, the astrophysical observatories of Potsdam and Meudon are still used as astrophysical observatories, but their historical heritage (instruments, books and archives) are dispersed while the South Kensington Solar Observatory in London is no more extant, having being embodied in the buildings of the Science Museum. In Italy, the two different cases of Rome and Palermo observatories are here examined: the original site of the Collegio Romano Observatory, where fr. Angelo Secchi carried out his remarkable studies on stellar and solar spectroscopy, is now impossible to visit and its collections are splitted into two parts, one being kept at the Copernican and Astronomical Museum and the other one at the Monte Porzio Catone Observatory. The rooms of the Collegio Romano Observatory could be used for educational purposes, remarking the importance of recovering the original site and its historical importance. This has been done at the Palermo Observatory, still in use as an astrophysical observatory, where a historical museum has been installed in the original floor of the Observatory, keeping the instruments and the setting the nearest possible to their original arrangement.
