Roman Formia on foot between centre and Castellone
An urban plan with museum and interiors optional and always subject to same-day official confirmation.
This route links the centre and Castellone, reading the layers of ancient and later Formia from public outdoor spaces.
Optional museum
The National Museum can provide context but is not a prerequisite. Check the official same-day notice; if closed, begin outdoors and never replace confirmation with old hours.
Castellone and interiors
Include the Cisternone or other interiors only with a confirmed visit. Roads, slopes and traffic require care, and the route never authorises entry to closed sites.
