Museo delle Mura belongs because it gives the map a dedicated city-walls destination at Via di Porta San Sebastiano, 18, 00179 Roma RM. This is not simply another Appian Way ruin: it is the named museum and walls site at the gate, offering a different way to approach Rome’s ancient defensive fabric from the baths, tombs and underground houses elsewhere in the selection. The supplied guidance allows 60–90 minutes.

Its location also makes it a practical bridge between central Rome planning and an Appian Way outing. The site is best reached by bus or on foot from the Appian Way gate, so route choice matters more than it does for a short street view at Ludus Magnus or Piramide Cestia. The exact place is Museo delle Mura at Via di Porta San Sebastiano, 18, rather than a broad pin for the Appian Way or the surrounding district.

Visitors should pay attention to the fact that some wall-walk sections may close independently. That means the museum and the walkable wall elements should not be treated as an inseparable guarantee. Check municipal museum hours and current section availability before travel.
