Via Principalis and Via Praetoria
East – West road and North – South road
Roman Forts were constructed to a general plan. This meant that a messenger from another fort would be able to find his way around the Lunt and go directly to the building he wanted, even if he had not been there before.
These two roads provide easy access to all parts of the fort. The Via Principalis connected the eastern and western gateways; the Via Praetoria ran from the southern gateway to an intersection with the Via Principalis.
