La
Sala Borsa (literally Stock Exchange Room) is a fantastic library with a huge ammount of batches, specially on the children and teenage section. But it's also an outstanding building which entrance is situaded about 20 meters far from the famous
Fontana del Nettuno. As you can guess from the name, it has not always been a library: from 1870s (in which it was built) to the World War II it was Bologna's stock exchange room . Afterwards it became a sports arena till 2001 in which the library was inaugurated. But the most amazing thing about this places is that, under the transparent floor, it's still possible to see some remains of
Felsina, the name that the etruscans gave to the city when thsy founded it on the 6th century BC.
