Feature type: name, no symbol
Segment grid: 7C1
The name is altogether difficult to read, and two letters seem beyond recovery.
Even though not represented with a symbol in the regular way, this stretch is in fact a crossroads: compare, for example, Tamannvna Mvnicipivm et Castellvm (1C2) and Dertona (2B5). Of these three, Z[.]gaza[.]na is perhaps the least readily comprehensible for the map's users.
