Casa a Graticcio, Roman residential structure in Ercolano, Italy.

Casa a Graticcio is a Roman house in Ercolano built with timber framing and infill of opus incertum covered in lime, covering about 180 square metres with rooms 2.9 metres high. A partly restored balcony rests on three brick columns above three street entrances: one leads upstairs by a staircase, one to a ground-floor flat via a corridor, and one to a taberna connected to the house. The lower flat has a courtyard with impluvium and a wooden winch for drawing water from the cistern.

The building was likely built in the first century as part of a densely populated residential area. The eruption of Vesuvius in 79 covered it with volcanic material and preserved the structures along with many everyday objects inside.

The name comes from the wooden framework visible in the walls, showing how poorer residents built their homes. You can still see where the family lived and worked in their daily life.

The building sits within the Herculaneum archaeological park, a large excavation site that is easy to visit. Watch for narrow walkways and uneven ground as you explore this house and the surrounding area.

Under the balcony, three entrances open onto the pavement: one leads upstairs by a staircase, one reaches a ground-floor flat through a short corridor, and the third serves a taberna connected to the lower apartment. The balcony itself rests on three brick columns standing on the sidewalk.
