Cisterna della Fontana del Calamo (Cistern of the Fontana del Calamo) is the ancient water cistern which provides the water for the famous spring. The Fontana del Calamo (Fountain of Calamus) is also named the Fontana delle Tredici Cannelle (Fountain of the Thirteen Spouts) because of its thirteen decorated spouts. The spring of Calamo was named after the swamps in the area, kalamos is the Greek word for reed, which grew around the spring. The Greek came to this place and used the spring for fresh water, the name stuck. The origin of the fountain is unknown, but there is a document about the extension of the water tanks from 1426. Today the fountain gets its water through modern pipes, but in ancient times the fountain drew water from a large cistern placed right in the walls behind it. The cistern was filled with water by an aqueduct from mount Conero.

The cistern is open to the public on certain festivities and for groups with reservation. The entrance is on the right side of the fountain. Tours are guided by guides from Ancona Sotterranea, a non-profit organization which explores the underground of the city. Beneath the cistern there are also tours into the Cisterns of Piazza Stamira and the Tunnels of the Viale della Vittoria. But while the cistern is an easy tourist visit with mostly level and dry floors and electric light, those tours are actually cave trekking tours. They require helmet, headlamp, and gum boots.
