Italy's Museum of the Imperial Forums recently unearthed

A stone's throw from the Coliseum is Rome's new, masterfully designed Museum of the Imperial Forums, in a brick complex built by Emperor Trajan in the 2nd century but long concealed beneath centuries of subsequent construction and rubble.

When excavation of Trajan's Markets revealed the walls and roofs of the complex, huge glass windows were added, allowing light to pour into the brick Great Hall, considered a model for vaulted structures built later in the capital. Smaller chambers line two sides of the hall with a dramatically displayed collection of ancient Roman sculptural fragments from several forums in the vicinity. The entrance to Trajan's Markets is on Via IV Novembre just above Trajan's Column.
