The Fontana delle 99 Cannelle is a symbol of the town of L’Aquila and was built near the Aterno way. The fountain commemorates the 99 castles which, according to local lore, Frederick II succeeded in uniting in order to found L’Aquila. Originally it was a public wash-house, though the exact source of the water is unknown. On the wall are tiles in a pink and white pattern and there are 99 spouts, most of which are from the mouths of gargoyles. It is said that there are no two gargoyles with the same features.
