Miseno is one of the frazioni of the municipality of Bacoli in the Italian Province of Naples. Known in ancient Roman times as Misenum, it is the site of a great Roman port.

The Piscina Mirabilis is an ancient Roman cistern on the Bacoli hill at the western end of the Gulf of Naples, southern Italy. It was one of the largest ancient cisterns. It was built under Augustus as evidenced by the building technique of opus reticulatum used in the walls.The cistern was dug entirely out of the tuff hill and was 15 metres (49 ft) high, 72 metres (236 ft) long, and 25 metres (82 ft) wide.
